The correct answer is B. A provirus is viral DNA incorporated into the host cell's DNA.
A provirus is a form of viral genetic material that has been integrated into the DNA of a host cell. This integration occurs after the virus infects the host cell and inserts its genetic material into the genome of the host. The provirus remains in a latent state, meaning it is not actively replicating, but it can become activated and start producing new virus particles under certain conditions.
Viral DNA, on the other hand, refers to the genetic material of a virus. It can exist in various forms, such as RNA or DNA, depending on the type of virus. Viral DNA is the complete set of genetic instructions that allow the virus to replicate and produce new virus particles. Unlike a provirus, which is integrated into the host cell's DNA, viral DNA exists as a separate entity within the virus particle.
Compare and contrast a provirus and viral DNA. (1 point)
A. A provirus is newly replicated viral DNA after injection.
B. • A provirus is viral DNA incorporated into the host cell's DNA.
C. • A provirus is the host cell's DNA that has been destroyed.
