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.
This DNA can be incorporated into host genome as a provirus that can be passed on to progeny cells. The retrovirus DNA is inserted at random into the host genome. Because of this, it can be inserted into oncogenes. Pol proteins are responsible for synthesis of viral DNA and integration into host DNA after infection. 2  Env proteins play a role in association and entry of virions into the host cell. 3  Possessing a functional copy of an env gene is what makes retroviruses distinct from retroelements.
