Best Answer

Polymerase Chain Reaction (PCR) testing is a technique to amplify a single or few copies of a piece of DNA across several orders of magnitude, generating thousands to millions of copies of a particular DNA sequence. This allows for easier identification of particular DNA segments and can be used to assist in the diagnosis of certain diseases.
