Which of the following techniques is used by researchers to carry out dna replication in vitro?

a.) northern blotting
b.) dna fingerprinting
c.) polymerase chain reaction

C.) POLYMERASE CHAIN REACTION is the technique used by researches to carry out DNA replication in vitro.

Polymerase Chain Reaction is identified as a powerful amplification technique that can generate an ample supply of a specific segment of DNA from only a small amount of starting material. This means that from a DNA template, specific segments of DNA can be replicated.
