This is the 1st heat-stable component used in PCR:
Correct answer: C. Taq-polymerase
- A. Taq-isomerase
- B. Taq-helicase
- C. Taq-polymerase
- D. Taq SSBp
Explanation
Taq-polymerase is a polymerase enzyme extracted from the heat-stable bacteria called Thermus aquaticus which lives in hot springs. The bacteria has its enzymes adapted to work in extreme heat making Taq polymerase a heat-stable compound.
