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).
Nucleic acid, which can be either DNA or RNA, encodes the genetic information that is necessary to make copies of the virus. The nucleic acid is surrounded by a protective protein coat, called a capsid. Some viruses are also surrounded by an outer membranous layer, called an envelope, made of lipid and protein.Capsid Morphology. The viral capsid is a protein coat that provides protection for viral nucleic acid and is a means of attachment to hostâs cells.It is composed of proteinaceous subunits called capsomeres.ou have free access to a large collection of materials used in a college-level introductory microbiology course.
