noun, plural ret·ro·vi·rus·es.

any of a family of single-stranded RNA viruses having a helical envelope and containing an enzyme that allows for a reversal of genetic transcription, from RNA to DNA rather than the usual DNA to RNA, the newly transcribed viral DNA being incorporated into the host cell's DNA strand for the production of new RNA retroviruses: the family includes the AIDS virus and certain oncogene-carrying viruses implicated in various cancers.

retrovirus

A virus, such as HIV, whose RNA codes for DNA, which is then inserted into some part of the host's DNA. This virus comes with its own special enzyme, called reverse transcriptase, which facilitates this insertion.

Scientific definitions for retrovirus

retrovirus

[ rĕt′rō-vī′rəs ]

Any of a group of RNA viruses whose RNA is used as a template inside a host cell for the formation of DNA by means of the enzyme reverse transcriptase. The DNA thus formed is inserted into the host cell's genome. Most retroviruses can cause cancer. Retroviruses also include HIV.
