The figure below shows three steps (A, B, C) of Polymerase Chain Reaction (PCR). Select the option giving correct identification together with what it represents ?
- A - Denaturation at a temperature of about 50ºC
- C - Extension in the presence of heat stable DNA polymerase
- A - Annealing with two sets of primers
- B - Denaturation at a temperature of about 98ºC separating the two DNA strands
The correct answer is: C - Extension in the presence of heat stable DNA polymerase
