Solution

If both assertion and reason are true but reason is not the correct explanation of assertion.

Retrovirus is an RNA-containing virus that converts its RNA into DNA by means of the enzyme reverse transcriptase. This enables it to become integrated into its host's DNA. Some retroviruses can cause cancer in animals they contain oncogenes (cancer-causing genes), which are activated when the virus enters its host cell and starts to replicate. The special properties of retroviruses make them useful as vectors for inserting genetic material into eukaryotic cells. The best-known retrovirus is HIV, responsible for AIDS in humans.
