| Retroviridae |
A retrovirus is a virus which has a genome consisting of two plus sense RNA molecules, which may or may not be identical. It relies on reverse transcriptase to perform the reverse transcription of its genome from RNA into DNA, which can then be integrated into the host's genome with an integrase . The virus itself is a storage form for its nucleic acid genome as well as a means of delivery of its genome into targeted cells, which constitute the infection. ...

| retrolisthesis |
Slipped disc (medical term: prolapsed intervertebral disc) is a condition in which, due to a tear in the outer fibrous ring, the central part of the intervertebral disc is protruding into the spinal canal. Most commonly this occurs in the lowermost part of the spine, especially between the fourth and fifth vertebral bodies and between the fifth vetrebral body and the sacrum. This protrusion usually occurs to one side of the spinal canal, at the point where a nerve root leaves the canal. ...

| retrovirus |
A type of virus that has RNA instead of DNA as its genetic material. It uses an enzyme called reverse transcriptase to become part of the host cells' DNA. This allows many copies of the virus to be made in the host cells. The virus that causes AIDS, the human immunodeficiency virus (HIV), is a type of retrovirus.
