Answer: The correct answer is- Polymerase chain reaction.

Polymerase chain reaction is a technique in molecular biology that is used to produce multiple copies of a piece of DNA molecule through multiple cycles of three stages that are-

1) Denaturation- The two DNA strands are separated ( so that template DNA are exposed) at higher temperature.

2) Annealing- Primers ( forward and reverse) are attached to the template DNA.

3) Extension- New DNA strand is synthesized using enzyme Taq polymerase that adds dNTPs ( deoxyribonucleoside triphosphate) according to the complementary sequences in the template.
