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.
(June 2008). One of the obstacles to treatment of the human immunodeficiency virus is its high genetic variability. HIV can be divided into two major types, HIV type 1 (HIV-1) and HIV type 2 (HIV-2).HIV-1 is related to viruses found in chimpanzees and gorillas living in western Africa, while HIV-2 viruses are related to viruses found in the endangered west African primate sooty mangabey.IV-1 viruses may be further divided into groups. The HIV-1 group M viruses predominate and are responsible for the AIDS pandemic. Group M can be further subdivided into subtypes based on genetic sequence data. Some of the subtypes are known to be more virulent or are resistant to different medications.
