Text Solution

Verified by Experts

The correct answer is:

Step : The DNA is being heated to separate the strands → Denaturation at 94–96°C

Step : Primers are binding to the single-stranded DNA → Annealing at 40–60°C

Step : DNA polymerase is synthesizing the new strand → Extension through Taq polymerase at 72°C

Step : Repeated cycles produce many copies → Amplified DNA.
