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. ...
