Question

When DNA is heated to 95 C,

A. the phosphodiester bonds of the DNA breaks.
B. strand separation of the double stranded DNA occurs.
C. amplification of the target DNA occurs.
D. Taq Polymerase synthesizes DNA by extending the primers.
E. primers anneal to DNA strands.

Answer 1

B. strand separation of the double stranded DNA occurs.

Step-by-step explanation:

When mammalian DNA is heated to about 95°C, the hydrogen bonds between the A-T and G-C base pairs in the DNA double strand will break apart, unwinding the double-stranded DNA.
