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.
In the appropriate cell, DNA viruses are able to program the cell to replicate the virus using the genes contained within the viral DNA genome. The extracellular form of a virus is known as a virion. For a DNA virus, the virion is composed of a set of DNA genes protected by a proteincontaining coat called a capsid.The coat is often characterized by regularity and symmetry in its structure and is capable of binding to and invading cells.ike all viruses, DNA viruses are small when compared to the cells they infect and as such are obligate intracellular parasites (parasites that can only replicate within cells).
