What is the difference between a prophage and viral DNA?(1 point) A prophage is the host cell’s DNA. A prophage is bacterial DNA. A prophage is viral DNA incorporated into the host cell’s DNA. A prophage is newly replicated viral DNA.

A prophage is a bacteriophage (often shortened to "phage") genome inserted and integrated into the circular bacterial DNA chromosome or exists as an extrachromosomal plasmid. This is a latent form of a phage, in which the viral genes are present in the bacterium without causing disruption of the bacterial cell.
