A scientist wаnts tо аmplify а segment оf DNA using PCR. The reactiоn mixture contains the template DNA, primers, nucleotides, and DNA polymerase. During the thermal cycling process, the DNA is first heated to separate the strands, then cooled to allow primers to bind, and finally heated again to allow the polymerase to synthesize new DNA. Which of the following correctly matches the PCR steps with their descriptions?
