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.
A virus is a submicroscopic infectious particle composed of a protein coat and a nucleic acid core, as shown in Figures 1 and 2. Viruses are similar in size to a large protein macromolecule, generally smaller than 200 nm in diameter.ther bacteriophages can infect a host and insert their DNA into the host DNA. Under certain conditions the viral DNA can detach and direct replication of new virus, eventually killing the host cell. Once inside the cell, the nucleic acid follows one of two paths: lytic or lysogenic, as shown in Figure 7.
