provirus
The precursor of an animal virus, usually a retrovirus; theoretically analogous to the prophage in bacteria, the p. is integrated in the nucleus of infected cells, and can be activated in response to certain stimuli.

pro·vi·rus (')prō-'vī-rəs n a form of a virus that is integrated into the genetic material of a host cell and by replicating with it can be transmitted from one cell generation to the next without causing lysis

pro·vi·rus (pro-viґrəs) 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, spontaneously or by induction, to produce a complete virus; it can also cause transformation of the host cell. proviral adj
