Question

compare and contrast a provirus and viral dna. (a point) a provirus is viral dna incorporated into the host cells dna. a provirus is the host cells dna that has been destroyed. a provirus is newly replicated viral dna after injection. a provirus is bacterial dna incorporated into the viral dna.

Explanation:

A provirus specifically refers to viral genetic material that has integrated itself into the host cell's genome (DNA). Viral DNA on its own is the genetic material of the virus, while a provirus is that viral DNA after incorporation into the host's DNA. The other options are incorrect: a provirus is not destroyed host DNA, not newly replicated viral DNA post-injection, and not bacterial DNA inserted into viral DNA.

Answer:

A. A provirus is viral DNA incorporated into the host cell's DNA.
