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 American biochemist Kary Mullis at Cetus Corporation; Mullis and biochemist Michael Smith, who had developed other essential ways of manipulating DNA, were jointly award… Spletpcr是聚合酶链式反应的简称，是一种酶促化学反应，可以在试管里将待测的目的基因在很短的时间内扩增五十万倍乃至上百万倍，大大提高了基因诊断的灵敏度，降低了分析的难度。pcr法是基因诊断中使用最多的方法。 overall average school https://nechwork.com

There are three main stages: Denaturing – when the double-stranded template DNA is heated to separate it into two single strands. Annealing – when the temperature is lowered to enable the DNA primers to attach to the template DNA.
