The polymerase chain reaction (PCR) is a scientific technique in molecular biology to amplify a single or a few copies of a piece of DNA across several orders of magnitude, generating thousands to millions of copies of a particular DNA sequence.

Modern PRC systems not only amplify a piece of DNA, but also make accurate qualitative and quantitative detections of nucleic acids and genotyping in real-time.
