Polymerase Chain Reaction ( PCR) is a technique that allows to quickly obtain millions of copies of a DNA sequence by an in vitro and automatic process. It is widely used in molecular biology applied to both research and diagnosis.
This page explains with text and videos how the PCR works and the amplification process.
