What occurs during the annealing stage of a PCR reaction?
A) The DNA strands separate
B) The DNA polymerase copies the template DNA
C) The primers bind to complementary sequences of the template DNA
D) The reaction stops

Question

Quizplus · Accepted Answer

During the annealing stage of a PCR reaction, the temperature is lowered to allow the primers to bind to complementary sequences on the template DNA. This is a critical step in the PCR reaction as it sets the template for the DNA polymerase to copy the DNA sequence.
