Explanation:
Detailed explanation-1: -PCR is based on using the ability of DNA polymerase to synthesize new strand of DNA complementary to the offered template strand. Because DNA polymerase can add a nucleotide only onto a preexisting 3’-OH group, it needs a primer to which it can add the first nucleotide.
Detailed explanation-2: -PCR essentially mimics cellular DNA replication in the test tube, repeatedly copying the target DNA over and over, to produce large quantities of the desired DNA.
Detailed explanation-3: -So the correct answer is “Taq polymerase"
