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.
When RNA viruses invade the human organism, they inject their RNA into the cytoplasm of the host cell. Once they are inside the cytoplasm, RNA can be used to synthesize proteins, and, eventually, to form replica viruses. There is a special category of RNA viruses, which is called retroviruses. These viral agents contain protein known in biology as reverse transcriptase. Once the retrovirus injects its RNA into the cell, reverse transcriptase transcribes the RNA into DNA (the operation that is the reverse of normal transcription).
