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.
Once in DNA form, the genetic information of HIV is incorporated as a provirus with the host cell DNA. The proviral genome can subsequently be transcribed into viral RNA that functions as mRNA for translation into HIV proteins and as genomes for the subsequent generation of the virus.IV is a relatively complex virus that is able to infect helper T cells chiefly due to a glycoprotein embedded in its envelope called gp120 (see Figure 1) that attaches to CD4, a protein found on the surfaces of the T cells.
