Here are all the possible meanings and translations of the word provirus.


  1. provirus(Noun)

    A virus genome, such as HIV, that integrates itself into the DNA of a host cell so as to be passively replicated along with the host genome.


  1. Provirus

    A provirus is a virus genome that is integrated into the DNA of a host cell. This state can be a stage of virus replication, or a state that persists over longer periods of time as either inactive viral infections or an endogenous retrovirus. In inactive viral infections the virus will not replicate itself but through replication of its host cell. This state can last over many host cell generations. Endogenous retroviruses are always in the state of a provirus. When a retrovirus invades a cell, the RNA of the retrovirus is reverse-transcribed into DNA by reverse transcriptase, then inserted into the host genome by an integrase. A provirus does not directly make new DNA copies of itself while integrated into a host genome in this way. Instead, it is passively replicated along with the host genome and passed on to the original cell's offspring; all descendants of the infected cell will also bear proviruses in their genomes. This is known as lysogenic viral reproduction. Integration can result in a latent infection or a productive infection. In a productive infection, the provirus is transcribed into messenger RNA which directly produces new virus, which in turn will infect other cells via the lytic cycle. A latent infection results when the provirus is transcriptionally silent rather than active.
