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.
All viruses have genes constructed from either deoxyribonucleic acid (DNA) or ribonucleic acid (RNA)âlong helical molecules that carry genetic information. All viruses have a protein coat that protects these genes, and some are wrapped in a viral envelope of fat that surrounds them when they are outside a cell.(Viroids do not have a protein coat and prions contain neither RNA nor DNA). virus is a microscopic organism that can replicate only inside the cells of a host organism. Most viruses are so tiny they are only observable with at least a conventional optical microscope.
