Choose the correct statement(s) about thermostable DNA polymerase used in PCR Q. Taq Pol has 5 3 exonuclease activity. R. Pfu Pol has 3 5 exonuclease activity. S. Tli Pol has no 3 5 exonuclease activity. P. Taq Pol has no proofreading ability. a. P and Q b. P, Q and R ons C. 2, R and s d. P, Q, R and S
option b is correct i.e. statements P, Q and R are correct.
Taq polymerase has 5'-3' exonuclease activity so statement 'Q' is correct.
Taq polymerase lacks proof reading activ...
