provirus
(redirected from proviruses)

   Also found in: Dictionary/thesaurus, Encyclopedia, Wikipedia 0.01 sec.
provirus /pro·vi·rus/ (pro-vi´rus) the genome of an animal virus integrated (by crossing over) into the chromosome of the host cell, and thus replicated in all of its daughter cells. It can be activated to produce a complete virus; it can also cause transformation of the host cell.
pro·vi·rus (prvrs, pr-v-)
n. pl. pro·vi·rus·es
The precursor or latent form of a virus that is capable of being integrated into the genetic material of a host cell and being replicated with it.

provirus
[-vī′rəs]
a stage of viral replication in which the viral genetic information has been integrated into the genome of the host cell. It may be activated spontaneously or by a specific stimulus to direct the cell to produce new virions to progress to a complete virus.

provirus [pro-vi´rus]
a DNA transcript of an RNA virus that migrates from the cytoplasm into the nucleus and integrates into the host genome by crossing over so that it will be thus replicated in the daughter cells.

provirus (prōvī´rus),
n a type of virus incorporated into a host cell's genetic material that transmits from one generation of cells to the next via cell replication without triggering the separation or decomposition of the cell.

provirus
the genome of an animal virus integrated into the chromosome of the host cell, and thus transferred to in all of its daughter cells.

Scientists from Tokyo-based Nihon University highlight the fact that latently infected cells harbour HIV-1 proviral DNA genomes integrated with heterochromatins, allowing for the persistence of transcriptionally silent proviruses.
The alternate, more sophisticated, and more "down the road" approach is to use molecular probes that seek, find, and destroy cells harboring HIV genomes--even those hidden in the cell as silent DNA proviruses.
Molecular epidemiologic studies have shown HTLV-1 proviruses to be remarkably stable genetically.
