A type of virus that uses of RNA as its genetic material. After infecting a cell, a retrovirus uses an enzyme called reverse transcriptase to convert its RNA into DNA (the hereditary material in humans). The retrovirus then integrates its viral DNA into the DNA of the host cell, which allows the retrovirus to replicate. HIV is a retrovirus.
