    Polymerase chain reaction is most useful in

    A)  DNA synthesis

    B)  DNA amplification

    C)  protein synthesis

    D)  amino acid synthesis

    Correct Answer: B

    Solution :

                     The Polymerase Chain Reaction (PCR) technique was developed by Kary Mullis in 1985. It generates microgram (\[\mu g\]) quantities of DNA copies of the desired DNA (or RNA) segment, present even as a single copy in the initial preparation in a matter of few hours. So, PCR is the most useful in DNA amplification. DNA synthesis is known as replication or duplication. Protein synthesis is known as translation.
