Polymerase Chain Reaction molecular biological method for amplifying DNA without using a living organism. PCR is commonly used in: Identification of genetic fingerprints. Diagnosis of infectious diseases. Diagnosis of virus diseases.

A T G CA TC G The four bases found in DNA are Adenine (A), Cytosine (C), Guanine (G) and Thymine (T).
