During PCR which enzyme is used to do polymerization of DNA fragments
Correct answer: C. Taq polymerase
- A. RNA polymerase
- B. DNA polymerase
- C. Taq polymerase
- D. DNA ligase
Explanation
Like DNA replication in an organism, PCR requires a DNA polymerase enzyme that makes new strands of DNA, using existing strands as templates. The DNA polymerase typically used in PCR is called Taq polymerase, after the heat-tolerant bacterium from which it was isolated (Thermus aquaticus).
