What is the role of the Taq polymerase enzyme in the polymerase chain reaction?
- A.To denature the DNA template
- B.To anneal the primers to the template
- C.To synthesize new DNA strands
- D.To cut the DNA into smaller pieces
Show correct answer & step-by-step solution
Correct answer: C — To synthesize new DNA strands
Solution
- PCR involves cycles of denaturation, annealing, and extension.
- Taq polymerase is derived from the thermophilic bacterium Thermus aquaticus.
- It adds nucleotides to the primer to extend the DNA strand at high temperatures.
- Hence the answer is (C).
