Any of a family (Retroviridae) of viruses
containing the genetic material RNA rather
than the more usual DNA. For the virus to
express itself and multiply within an
infected cell, its RNA must be converted to
DNA. It does this by using a built-in enzyme
known as reverse transcriptase (since the
transfer of genetic information from DNA to
RNA is known as transcription, and
retroviruses do the reverse of this).
Retroviruses include those causing AIDS and
some forms of leukemia. See immunity.
