Definition of PCR

Polymerase chain reaction (PCR) is used for a wide range of applications such as cloning, gene expression analysis, genotyping, sequencing and mutagenesis.

PCR is a technique that enables many copies of a specific DNA region to be amplified. PCR relies on thermostable DNA polymerase, Taq polymerase and requires DNA primers designed to specifically for the DNA region of interest.
