What is the main purpose of PCR?

Monoclonal antibody production . Hybridoma production. Amplifying multiple copies of the specific segment of DNA (gene) . All of the above .

Amplifying multiple copies of the specific segment of DNA (gene) .

PCR stands for Polymerase Chain Reaction. In this reaction, multiple copies of the gene (or DNA) of interest is synthesised in vitro using two sets of primers (small chemically synthesised oligonucleotides that are complementary to the regions of DNA) and the enzyme DNA polymerase.
