A provirus is a virus genome that is integrated into the DNA of a host cell.In the case of bacterial viruses (bacteriophages), proviruses are often referred to as prophages.his can result in the destruction of its host cell because the cell's protein synthesis machinery is hijacked to produce more viruses. Proviruses may account for approximately 8% of the human genome in the form of inherited endogenous retroviruses.
One, called gag, gives rise to the inner shell where the virusâs genes are stored. Another, called env, makes knobs on the outer surface of the virus, that allow it to latch onto cells and invade them. And a third, called pol, makes an enzyme that inserts the virusâs genes into its host cellâs DNA.It turns out that the human genome contains segments of DNA that match pol, env, and gag.Lots of them.Scientists have identified 100,000 pieces of retrovirus DNA in our genes, making up eight percent of the human genome.ne, called gag, gives rise to the inner shell where the virusâs genes are stored.
