The pcr steps

WebbPCR involves a process of heating and cooling called thermal cycling which is carried out by machine. 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. WebbD. Caetano-Anollés, in Brenner's Encyclopedia of Genetics (Second Edition), 2013 Abstract. The polymerase chain reaction (PCR) is a basic molecular technique used for amplifying target sequences from a DNA template in an exponential manner. This is accomplished by using thermal cycling, a process in which a solution that includes DNA is repeatedly …
