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).
Retrovirus. Retroviruses are enveloped viruses that belong to the viral family Retroviridae. A retrovirus is an RNA virus that is duplicated in a host cell using the reverse transcriptase enzyme to produce DNA from its RNA genome. On infection, the single-stranded RNA viral genome and the enzyme enters the host cell.he viral genome is released into the host cell, from which a copy of DNA is made by the help of the enzyme reverse transcriptase. The cDNA is integrated into the host chromosome. The virus remains unexpressed until the host's immune system is stimulated.
