What is a Polymerase chain reaction?

Polymerase chain reaction or PCR is a specific method used to synthesize millions of copies of DNA of specific pathogens. These pathogens can be bacteria or viruses.

The Polymerase Chain reaction consists of four steps. It is an enzymatic method for the detection of specific DNA in the sample.
