Answer 2

A prophage is a bacteriophage (often shortened to "phage") genome inserted and integrated into the circular bacterial DNA chromosome or existing 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. Pro means ''before'', so, prophage means the stage of a virus in the form of genome inserted into host DNA before attaining its real form inside host.
