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.

B. strand separation of the double stranded DNA occurs.

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.

Virchow was a German scientist whose most important work was in the filed of cellular biology and pathology.His scientific experiments and examinations aimed to disprove the idea of spontaneous generation. This idea is based on an assumption that life can spontaneously appear out of non-living matter. After years of scientific work he concluded that only living cells can produce other cells, or that only life can produce life.Therefore, if it was somehow proven that cells can be generated from non-living matter, that would disprove his findings.
