Certain RNA viruses that infect animal cells carry within the viral particle an RNA-dependent DNA polymerase called reverse transcriptase.
The RNA viruses that contain reverse transcriptases are known as retroviruses (retro is the Latin prefix for “backward”) because the genetic information flows from RNA to DNA rather than from DNA to RNA.
Reverse transcriptase produces DNA from viral RNA

Some retroviruses, classified as RNA tumor viruses, contain an oncogene that can cause the cell to grow abnormally.
The first retrovirus of this type to be studied was the Rous sarcoma virus.
Another important class of retroviruses includes human immunodeficiency virus (HIV), identified in 1983, which causes acquired immunodeficiency syndrome (AIDS).
