Splet중합효소 연쇄 반응(重合酵素連鎖反應, 영어: polymerase chain reaction, PCR)은 DNA의 원하는 부분을 복제·증폭시키는 분자생물학적인 기술이다. The polymerase chain reaction (PCR) is a method widely used to rapidly make millions to billions of copies (complete or partial) of a specific DNA sample, allowing scientists to take a very small sample of DNA and amplify it (or a part of it) to a large enough amount to study in detail. PCR was invented in 1983 by … Prikaži več PCR amplifies a specific region of a DNA strand (the DNA target). Most PCR methods amplify DNA fragments of between 0.1 and 10 kilo base pairs (kbp) in length, although some techniques allow for amplification of … Prikaži več PCR has a number of advantages. It is fairly simple to understand and to use, and produces results rapidly. The technique is highly sensitive with the potential to produce millions to … Prikaži več One major limitation of PCR is that prior information about the target sequence is necessary in order to generate the primers that will allow its selective amplification. This means that, typically, PCR users must know the precise sequence(s) upstream of the target region on … Prikaži več In practice, PCR can fail for various reasons, such as sensitivity or contamination. Contamination with extraneous DNA … Prikaži več Selective DNA isolation PCR allows isolation of DNA fragments from genomic DNA by selective amplification of a specific region of DNA. This use of PCR augments many ways, such as generating hybridization probes for Southern Prikaži več • Allele-specific PCR or The amplification refractory mutation system (ARMS): a diagnostic or cloning technique based on single-nucleotide variations (SNVs not to be confused with Prikaži več The heat-resistant enzymes that are a key component in polymerase chain reaction were discovered in the 1960s as a product of a microbial life … Prikaži več
