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.

Retroviruses belong to the Retroviridae family of viruses. Their genetic material consists of ribonucleic acid (RNA), instead of deoxyribonucleic acid (DNA). Viruses of this type also contain reverse transcriptase. Retroviruses are known to lead to certain types of cancers in both humans and animals, as well as a range of viral infections. Human Immunodeficiency Virus (HIV), the virus that causes Acquired Immune Deficiency Syndrome (AIDS), is one example.
