What are retroviruses? How do they reproduce and what is the role of the enzyme reverse transcriptase?

Retroviruses are viruses whose genetic material is RNA. HIV and the virus of SARS (severe acute respiratory syndrome) are instances of retrovirus.

These viruses inoculate their RNA into the host cell and within the cell the viral RNA is reversely transcript into DNA. DNA made from the viral RNA then commands the synthesis of viral proteins for the assemblage of latest viruses and the breaking of the host cell to liberate them outside.
