Retroviridae is a family of enveloped viruses that replicate in a host cell through the process of reverse transcription. A retrovirus is a single-stranded positive-sense RNA virus with a DNA intermediate and, as an obligate parasite, targets a host cell.ithin the cell, reverse transcriptase creates a complementary strand of DNA from the retrovirus RNA and the RNA is degraded; this strand of DNA is known as cDNA (4). The cDNA is then replicated, and the two strands form a weak bond and go into the nucleus (5).
Noun. 1. retrovirus-any of a group of viruses that contain two single-strand linear RNA molecules per virion and reverse transcriptase (RNA to DNA); the virus transcribes its RNA into a cDNA provirus that is then incorporated into the host cell. animal virus-an animal pathogen that is a virus.etÂ·roÂ·viÂ·rus. Any of a group of viruses containing RNA in which the RNA can convert to DNA inside a cell. Some retroviruses cause cancer in humans. The virus that causes AIDS is a retrovirus.
