Question

Enzyme required for polymerase chain reaction (PCR) is

• A. RNA polymerase
• B. Ribonuclease
• C. Taq polymerase
• D. Endonuclease

Answer 1

The correct option is C Taq polymerase

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.

So, option C is the correct option.
