Question

Why is Taq polymerase used in a polymerase chain reaction (PCR)? a. Unlike other DNA polymerases, Taq polymerase is not inhibited by dideoxy nucleotides. b. Taq polymerase is more efficient than other DNA polymerases. c. Taq polymerase has proofreading activity and thus makes fewer errors than other DNA polymerases. d. Unlike other DNA polymerases, Taq polymerase is heat stable and survives the denaturation step in PCR. e. Taq polymerase can produce DNA from an RNA template, unlike other DNA polymerases.
