Which of the following temperature sequences correctly represents the three main steps of a standard PCR cycle?
Show answer and explanation
Correct answer: 95°C, 55°C, 72°C
A standard PCR cycle consists of denaturation (approx. 95°C), annealing (approx. 55°C), and extension (approx. 72°C). This sequence allows DNA strands to separate, primers to bind, and DNA polymerase to synthesize new strands respectively.
