Nightmare Before Christmas | Analysis

incubus Before Christmas AnalysisTim Burton rings in my ears as angiotensin converting enzyme of Hollywoods most eccentric directors. There is a distinct and unique phenomenon in his films the music genre of his most films are betwixt animation films and real person films his animation films overturn the field of traditional fairy tales, showing the darkness of horror, provided did not cash in adepts chips us the feel of fear. Nightmare before Christmas, which reflects his typical paradigm, is a fantasy mixed of horror, magic, darkness, holidays, the jolly guys, and an interest skeleton.The features of Nightmare before Christmas f al unitary in a similarity with Bakhtins theory of carnivalesque. In Bakhtins view, e genuinelyone lives a carnivalistic life as long as those carnival laws. His feel of carnival is full of grotesque realism, which evict get still of the horrable things in the world. And the grotesque style quarter too turn the world into a bright and well-p rovided one. (Bakhtin,1989). There is everlastingly a feel of carnival surrounded in Nightmare before Christmas. Because of the feel, listening can get away from the fear successfully.On the other hand, Bakhtin believes that carnivalistic life is a life drafts hu soldieryship out of its usual rut it is to some extent life turned in stance out, the set aside side of the world.( Bakhtin,1989) Similarly, Burton sets two worlds to make out a comparision the human world and underground world the grotesque world of Halloween and the joyful world of Christmas. The confrontation of the two worlds represents Burtons inclination. The happy world is boring while the eerie wolrd is vivid and interesting. In my Nightmare before Christmas lingers on the edge of conventional culture and popular culture, it challenges the conventional culture and queries on the popular culture. So Burton makes an utmost effort to prove the rationality of his subversion in this film.It receives delight in tal king about Burtons Gothic darkness of horror. The story happens in the world of ghosts and monsters where we are totally un familiar. The vampire bats, red eye demon , black monsters and even the wretched green, these gothic images are everywhere in the film. They stand in stark contrast to the simplicity of traditional animation films. However, the audience feel more than closer to them and come to realize their subsistence status trenchantly.The American animation films have a heroism complex, hardly Burton deconstructs our expectation of the traditional hero. In Nightmare before Christmas, the character Jack is frightful and he has no mission to save the world. Other character is treated equally, eg. the pet comes along with Jack is soul of a dog instead of a brilliant white horse. More primary(prenominal)ly, Burton wants to create a balance between creepy and interesting. So he defends life to the grotesquery Jack who literally is virtuous. He demonstrates the characters in dividual emotions and action at law which has no relationship with hero. Specificly, the modeling of Jacks eyes are expert two black holes which intelligent reserve expression to the meaning of the character.Lets turn to the other film No Country for Old handsIn this film No Country for Old Men the genre pushes the envelope of sanity. It is an unconventional westerly film, mixed with action, crime drama and dark humor. The McCarthys novel No Country for Old Men is an model vehicle for the Coen brothers, who have used violence and emptiness laced with dark humor as an esthetical aesthetic in their directing careers.The films greatest achievement is its ability to transport the audience into a world where the foreordination, death, fears, choices, morals and realities of life are strikingly brought to life and make the audience reflect upon and look support with careful consideration after the whole experience. The violence and bleakness of it all is not to simply provoke r eaction or engage the audience, it is to tell a story and impart an experience of great intention, to which the Coens have brilliantly succeeded.To some extent, this film is a character study of Sheriff Bell, an honest lawman who is wise, observant, grounded in reality, and has a long memory. No Country for Old Men is really his story. And also, The Coen brothers direction of the contingently intense chase scenes between Chigurgh and Moss are masterful, evoking emotions of suspense to the highest level and pushing the audience to the very edge of their seats.At the equivalent time the movie is a character study on the effects of evil and innocence lost, an geographic expedition on the themes of fate and chance, an analysis of the freedom to choose and its consequences, a reflection on evil and good as forces of society and the investigation of basic human emotions such as hope, fear, love, violence and aspiration in the face of a variety of situations.The ending of the film is a bout death. Faced with the overwhelming fact of death, all of us humans find meaning only by making up their own spectral codes. The murderers code, the good experient boys code, the sheriffs code, the wifes codethey are all equally meaningless, equally inadequate in the face of death, but they are all perfectly legitimate responses to the fact of universal death. The film is also about predestination and free will, Chigurgh doesnt believe in free will, I got here the equal way the coin did , he is almost like a robot , and scientifically he is totally right we dont have free will , Chigurgh is not guilty , he just has killer genes and his mother didnt hug him so thats why he turned out to be this way, there are no choices in matter , just cause and effect , only quantum psychics can show some difference.In conclusion, Film genres can take culture as very important elements into consideration. And also, we can characterize a culture by its genre set. Obviously through the film re view, we can see that genre can function as a tool to define and specify a culture.Heroes and Villains Historical AnalysisHeroes and Villains Historical AnalysisHeroes, Villains or some(prenominal)? Austin RappelWhat I found most interesting in this weeks readings was the myths behind the men special(prenominal)ally Ulysses S. Grant, general in chief of the joined States Army, William T. Sherman, general in The United States Army and Abraham capital of Nebraska, president of the United States. Grant was considered a drunk, Whatever happened, the story of his drinking became a staple of gossip in the old army. (McPherson, pg.114) Sherman was considered crazy But Sherman could never entirely escape the reputation of madness (McPherson, pg 114) Lincoln was considered passive a basic trait of character evident throughout Lincolns life the necessary passivity of his nature. (McPherson, pg. 206) I ideate it is important to determine if these things were true or if there is overflow ing evidence to ever know for reliable the mindset or character of the men that are know to us as the men that delimitate and ultimately were the victors of the Civil War.Grant quickly rose through the ranks during the Civil War command of a brigade, a division, an army (Army of Tennessee), an army group, an all of the armies of the United States. (McPherson, pg 110) These accomplishments are a big contrast to what one could consider could be an accomplished by a drunkard. Brooks Simpson , a biographer concluded, Although Grant sometimes took a drink during the war, and may on occasion have taken two, his colleagues who knew him best and were in the best coif to observe him were unanimous in their testimony that he was rarely if ever drunk. (McPherson, pg. 114) Grant was also minded(p) the reputation as a butcher when the general most deserving of the title was Robert E. Lee. (McPherson, pg 113)Sherman is best known for his March to the Sea a march of over 700 miles, in which p sychological warfare was used in order to stop the war. As tell in McPherson, The terror that his soldiers provoked among Southern whites was a power, he wrote, and I intended to utilize it to humble their pride, to follow them to their inmost recesses, and to make them fear and dread us We cannot change the hearts and minds of those people of the South, but we can make war so terrible and make them so sick of war that generations would pass away before they would again appeal to it.(McPherson, pg. 124) As stated in the article by Matt Carr, General Shermans March to the Sea, Shermans plan was to attack the infrastructure of the southwestern and therefore end the war After more than cardinal years of violent and seemingly acolloidal mousseess conflict, Sherman had decided to take the conflict beyond the battlefield and subject Georgia to a level of bareness that would make its population realise that war and ruin are synonymous terms. (pg. 30) Its hard to imagine that these st rategies were those of a crazy man.Lincoln, the 16th president of the United States and the author of many documents most notably the Emancipation resolve was seen at least by one biographer, David Herbert Donald, to be passive. However, as stated in McPherson, at the very outset of his presidency Lincoln demonstrated traits that were the opposite of what Donald calls his essentially passive personality. (McPherson, pg. 207) Its hard to believe that the man that set into motion the Civil War and wrote one of our most historical documents has a passive personality. maybe the passivity noted by some is more a compassion than anything else. As stated in, Lincolns Legacy, Lincoln Lives Through His Words by Gail Fineberg, Lincolns first draft of the Emancipation Proclamation, which he presented to his cabinet on July 22, 1862. cipher liked it Sellers said. Lincoln came back to his cabinet with a second draft in September, and admonished members to comment not on substance but on his s tyle. (pg 38) The quote goes without saying to the mindset of a determined man more so to the mindset of a passive man.Although it may never be known the actual character of Grant, Sherman orLincoln, it will be leftfield up to the readers and historians perceptions of whether are not these men were heroes, villains or maybe a little of both during and after the Civil War. It goes without saying that these men, provided viewed, will always be remembered for the mark they left on the Civil War and wars to come.Polymerase filament Reaction (PCR) Optimization ParametersPolymerase Chain Reaction (PCR) Optimization ParametersIGHODARO OGHOGHO UYIOSAPolymerase chain reaction (PCR) Evaluation of different optimization parameters for appropriate PCR process.AbstractPCR is a dodge used to produce relatively large steps of a specific deoxyribonucleic acid sequence. The intersectionivity of PCR method depends on different reaction conditions such as the soaking up of the desoxyribonuclei c acid scout, concentration of magnesium ions, deoxyribonucleic acid guidebook dilution and polymerase concentration. The aim of this study was to find optimal reaction conditions required for appropriate PCR process. To check the elucidate conditions the agarose colloidal mousse and polyacrylamide gel electrophoresis were used. One one, strong amplified band and no panoptic product describe the most sufficient amount of given conditions. In the results of this experiment, the most suitable anneal temperature was 62oC, the most prim amount of concentration of magnesium was 2nMol, and the best template dilution was 2l. The important parameters evaluated in this experiment were template optimisation, annealing temperatures and magnesium chloride concentrations with and without touchdown PCR. IntroductionPCR is a simple, enzymatic assay, which allows for the addition of a specific DNA disassemble from a complex pool of DNA. PCR can be done using source DNA from a variety of tissues and organisms, including peripheral blood, skin, hair, saliva, and microbes. Only trace amounts of DNA are needed for PCR to generate enough copies to be analysed using conventional science laboratory methods. For this reason, PCR is a sensitive assay (Lilit andNidhi 2013).To carry out a PCR it is essential to have the following reagents DNA template, forward and reverse primers, PCR buffer, magnesium chloride (MgCl2), dNTP and DNA Taq polymerase.The annealing temperature allows for the annealing of the primers to the iodin stranded DNA. It depends on the length and composition of the primers. If the temperature is too high, indeed the primers will not anneal correctly, and if the annealing temperature is too low then the primers will anneal non-specifically (Hecker et al. 1996).Magnesium ions interact with the DNA polymerase enzyme during this process. The magnesium ion interacts with negatively charged molecules in the reaction. Positive ions of magnesium interact with the negatively charged DNA strands to mask the forces of incompatibility (Markoulatos et al. 2002).Template DNA is a fragment of DNA which is needed to create required copies.DNA Taq polymerase is a polymerase enzyme, which is essential for DNA replication, this means that DNA polymerase synthesizes DNA molecules from their nucleotide building blocks (Huang et al. 1992). The nucleotides include the four bases adenine, thymine, cytosine, and chiliad (A, T, C, G) that are found in DNA. These act as the building blocks that are used by the DNA polymerase to create the resultant PCR product.During this experiment, two methods were used to visualise the PCR products organise. These were Polyacrylamide gel electrophoresis (PAGE) and Agarose gel electrophoresis method. ionophoresis is a insularity procedure which is based on the separation of DNA fragments by size, shape and charge. The pool stick of this process is the mobility of ions in an electric field (nucleoid acids, which a re negatively charged migrate to the anode positive electrode) (Stellwagen, 1998). shoot forThe aim of this experiment was to assess which parameters as annealing temperature, concentration of magnesium, and template DNA sour DNA amplification efficiency and specificity.2.0Materials and methodsThis section was divided into two parts. In part A, a PCR reaction 1 set-up using optimized PCR mastermix was done, while in part B, a PCR reaction was set-up to test four different variables to optimise a PCR reaction.2.1 post ASetting up the PCR reactionA mastermix enough for four reactions was made. 30l of H2O, 50l of 2X PCR mastermix and 4l each(prenominal) of forward and reverse primers were pipetted and mixed in an Eppendorf tubing from which, 24l of the mastermix was pipetted into three separate PCR tubes (i.e. tube 1, 2, and 3). 1l of sample DNA, 1l of 1/10 diluted DNA and 1l of H2O were added to each tubes singly and each amplified on a PCR block running the following programmeDe naturing step done at 94oC for two transactionsAmplification step done at 94oC for 30 seconds, 55oC for 30 seconds and 72oC for 1 minute. This step was recurrent for 35 cycles.Finally, the extension step was done at 72oC for 3 minutes.Agarose gel electrophoresis (2% agarose gel for PCR)An agarose gel was submerged in a gel tank filled with TBE buffer. Then 5l of gel loading buffer was added to each sample and mixed. Next, the first well was sloshed with the molecular(a) pack marker and then 10l of each sample was loaded into each respective wells. Next, the gel was run for 45 minutes at 80V.Finally, the gel was visualised on the gel documentation system to show separation and migration of the DNA.2.2Part BPCR optimisation reactionFor this protocol, PCR reactions were set up and individual components of the reactions were alter in other to optimise them as followsAnnealing temperature optimisation 17.75l of water, 2.5l of 10x reaction buffer, 0.75l of Magnesium Chloride (50mMol ), 0.5l of dNTPs, 1l each of forward and reverse primers, 0.5l of Taq polymerase and 1l of DNA were pipetted into 5 separate tubes (i.e. tube 1, 2, 3, 4, 5) which were then rumpd on a gradient PCR block, with one tube at each of the following temperature 46oC, 52oC, 55oC, 58oC, and 65oC. Next, the PCR block was set to the following programmeDenaturing step at 94oC for two minutesAmplification step at 94oC for thirty seconds, 46-65oC for thirty seconds, and 72oC for one minute. This stage was repeated for thirty-five cycles.Finally, the extension step was done at 72oC for three minutes.Template optimisationA PCR mastermix containing 13.75l of water, 2.5l of 10x reaction buffer, 0.75l of 50mMol magnesium chloride, 0.5l dNTPs, 1l each of forward and reverse primer and 0.5l of Taq polymerase were pipetted into five tubes. Next, 5, 2, 1, 0.1, and 0.01l of template DNA and, 0, 3, 4, 4.9. 4.99l of H2O were added to each tubes respectively. Next, the tubes were then amplified on a PCR bloc k using the alike cycle parameters as set out in part A.Magnesium concentrationA PCR mastermix mastermix containing 16l of water, 2.5l of 10x reaction buffer, 0.5l dNTPs, 1l each of forward and reverse primer, 0.5l of Taq polymerase and 1l of DNA were pipetted into five tubes (i.e. tube 1, 2, 3, 4, and 5). Next, a Mgcl2 dilution was prepared to get a final Mgcl2 mMol of 0.5, 1.5, 2, 3 and 5mMol which were then added to each tubes respectively to give a final volume of 25l. Next, the tubes were then amplified on a PCR block using the same cycle parameters as set out in part A.Touchdown PCRA PCR mastermix was prepared using the same variables outlined for magnesium concentration.Then the touchdown PCR programme used was as follows94C for 3 minutes then94C for 30 seconds, 64C for 30 seconds and 72C for one minute for three cycles,94C for 30 seconds, 61C for 30 seconds, and 72C for one minute for three cycles,94C for 30 seconds, 58C for 30 seconds, and 72C for one minute for three cycl es,94C for 30 seconds, 55C for 30 seconds, and 72C for one minute for three cycles,94C for 30 seconds, 53C for 30 seconds, and 72C for one minute for thirty cycles, and finally 72C for three minutes.Sample preparation and polyacrylamide gel electrophoresisAfter all the different optimisation protocols, the samples to be loaded into the gel were prepared by adding 5l of loading buffer to each PCR reaction and mixed. Next, 5l of DNA ladder was pipetted into the first well while 10l of sample were pipetted into each designated wells. The gel was then run at 100V for 45 minutes. After which, the gel was recovered and placed in a weighing boat containing 1x TBE buffer. Next, 5l of ethidium bromide was carefully introduced into the weighing boat and left for 10 minutes before visualisation with a gel documentation system.3.0ResultPCR reactions were set up in 5 different PCR tubes with all the required components for complete PCR reaction , save for a particular factor which was varied to ascertain the optimal concentration necessary for the production of the highest amount of pure specific product. The results obtained from these various optimised factors are represented in the gels below.Part AOptimized PCR1l of DNA template was loaded in the well labelled neat DNA and it revealed the highest amount of product organise, the well containing a 1/10 diluted DNA had a much lower amount of product organize while the well with the water blank yielded no product. Also, unspecific products were not create.Figure 1 Optimised PCR agarose gel.Part BThe results of different PCR optimisation reactionsPCR annealing temperature optimisationFigure 2 PCR annealing temperature optimisation polyacrylamide gel. discover L-molecular weight ladder, road 1- 48c, highway 2- 52c, lane 3- 55c, lane 4- 62c, lane 5- 65c, unspecific product, specific product.From Figure 2 above, there are three unspecific products form in lane 1, a greater specific product with insignificant unspecific product form in lane 2, insignificant unspecific products make in lane 3 and there is also a decrease in the effectiveness of the specific product organize compared with that of lane 2. plot in lane 4, there is a minor decrease in the colour of the specific product make thus, the intense metre of the specific product formed (i.e. there is a strong amplification here) and in lane 5, there is a major decrease in the measuring stick of specific product formed. Therefore, the criterion of the product decreases as the quantity of the template DNA decreases, and the quantity of the specific and unspecific products step-ups as the quantity of the template DNA increase.Template dilution optimisationFigure 3 Template dilution optimisation polyacrylamide gel.Key L -molecular weight ladder, lane 1- 5l, lane 2- 2l, lane 3- 1l, lane 4- 0.1l, lane 5- 0.01l template DNA, specific product, unspecific product.From the gel above, there are three unspecific products formed in lane 1 and als o the colour of the specific product formed is high, the unspecific product formed in lane 2 is insignificant and the specific product formed is greater in saturation (i.e. has a higher amplification) compared with that of lane 1, in lane 3 and 4, the intensity of the specific product formed decreased compared with that of lane 2, while in lane 5, there is a major decrease in the intensity of the specific product formed. Therefore, the quantity of the product decreases as the quantity of the template DNA decreases, and the quantity of the specific and unspecific products increases as the quantity of the template DNA increase.Magnesium dilution optimisationFigure 4 Magnesium dilution optimisation polyacrylamide gel.Key L -molecular weight ladder, lane 1- 0.5mmol, lane 2- 1.5mmol, lane 3- 2mmol, lane 4- 3mmol, lane 5- 5mmol, specific product, unspecific product.Form the gel above, there is an unspecific and a specific product formed in lane 1, in lane 2 there is a decrease in the i ntensity of the unspecific product formed and also there is an increase in the amount of specific product formed. In lane 3, there were no production of unspecific products and the intensity of the specific product formed remained high. In lane 4, there is evidence of the presence of an unspecific product formed but the intensity of the specific product formed remained high. While in lane 5, there is a minor reducing in the intensity of the specific product formed while there is visible presence of formation of unspecific products.Magnesium touchdown optimisationFigure 5 Touchdown magnesium concentration optimisation.Key L molecular weight ladder, lane 1- 0.5 mMol, lane 2- 1.5 mMol, lane 3- 2mMol, lane 4- 3 mMol, lane 5- 5mMol, unspecific product, specific product.From the gel above, in lane 1, the intensity of the unspecific product formed is the same with that of the specific product formed. While in lane 2, 3 and 4, the intensity of the specific products formed are the same wh ile the intensity of the unspecific products gradually decreased. There was no unspecific product formed in lane 5, however there was a reduction in the intensity of the specific product formed compared to that of lane 4. preachingThis experiment was performed to evaluate different optimisation protocols to optimise PCR reactions.For the PCR reaction using an optimised PCR mastermix in part A, the highest amount of products formed was observed in the well containing 1l of DNA template.The annealing temperature is the most important optimisation, because it can have an influence on the specificity of the reaction. If the temperature is too high, the hybridization will not take place thus, templates and primers remain dissociated. If the temperature is too low, mismatched hybrids will occur. Correct annealing temperature must be low enough to start hybridization between template and primer, and also high enough to prevent forming mismatched hybrids (Roux, 2009). check to the results from annealing temperature optimization polyacrylamide gel (Figure 2), the most suitable annealing temperature was 62oC, because the band was clear and single as opposed to the 48oC, 52oC and 55oC, where the smears (i.e. unspecific products) were shown. The intensity of the band in 62oC was the strongest compared with that of 65oC.The most suitable template dilution for PCR was 2l, because it gave in the polyacrylamide gel in Figure 3, the most bright, single band with very low amount of unspecific products formed.Besides, annealing temperature and template dilution parameters, PCR reaction components could also lead to non-specific amplification. Two variables, which are reported to greatly influence the specificity of the PCR reaction, are magnesium and dNTP concentration (Dwivedi et al. 2003).For magnesium dilution touchdown (Figure 5), the molarities at 1.5, 2 and 3mMol showed very similar amount of products formed indicating the importance of the magnesium in PCR amplification while for magnesium dilution without touchdown (Figure 4), it was found that 2mM yielded the best results. Magnesium concentration is known to play a critical role in amplification as it can hit DNA strand denaturation, primer annealing specificity and enzyme fidelity. These observations are in agreement with earlier studies (Innis et al. 1990 Eeles et al. 1993). Even apprise incubations of a PCR mix at temperatures significantly below theTmcan result in primer-dimer formation and nonspecific priming. Hot-start PCR methods (Erlich et al. 1991Ruano et al. 1992) can dramatically reduce these problems.In this experiment, two methods were used to visualise the PCR products formed. They are, Polyacrylamide gel electrophoresis (PAGE) and Agarose gel electrophoresis. Agarose gel is the most popular medium for the separation of moderate and large-sized nucleic acids and have a wide range of separation but a low resolving power, since the bands formed in the gels tend to be indistinct and give out apart. This is a result of pore size and cannot be largely controlled (Stellwagen, 1998). However, Polyacrylamide gels are normally more sticky to prepare and handle, and it requires a longer time for preparation than agarose gels. However, polyacrylamide gels have a greater resolving power, can accommodate larger quantities of DNA without any significant loss in resolution and the DNA obtained from polyacrylamide gels is extremely pure (Guilliatt, 2002). Hence, they are better than agarose gels. It should be noted that polyacrylamide is a neurotoxin (when unpolymerized), but with proper laboratory care it is no more dangerous than various commonly used chemicals in the laboratory (Budowle Allen, 1991). finisOptimisation of Polymerase Chain Reaction is very important for PCR performance to minimize failures, avoid the production of non-specific products and increase specificity of the reaction. The knowledge of proper conditions allows to use PCR correctly and to receiv e good results.According to the results of the research the most suitable annealing temperature was 62oC, the most proper amount of concentration of magnesium was 2nMol, and the best template dilution was 2l.Those parameters give DNA amplification specificity and efficiency.
