From Wikipedia, the free encyclopedia. A retrovirus is any virus which copies itself as part of the cell's DNA by reverse transcribing its RNA. Since the cell cannot proofread the step in which RNA is converted back to DNA, errors often go unnoticed.This makes the exact sequence of a retrovirus's RNA change often.rom Wikipedia, the free encyclopedia.

retrovirus A virus whose genetic material consists of RNA and which is able, by means of the enzyme reverse transcriptase, to manufacture its DNA equivalent and insert it into the genome of its host species.icensed from Columbia University Press. retrovirus, type of RNA virus that, unlike other RNA viruses, reproduces by transcribing itself into DNA. An enzyme called reverse transcriptase allows a retrovirus's RNA to act as the template for this RNA-to-DNA transcription.
