<P> Group VI includes: </P> <Ul> <Li> Family Metaviridae </Li> <Li> Family Pseudoviridae </Li> <Li> Family Retroviridae--Retroviruses, e.g. HIV </Li> </Ul> <Li> Family Retroviridae--Retroviruses, e.g. HIV </Li> <P> Both families in Group VII have DNA genomes contained within the invading virus particles . The DNA genome is transcribed into both mRNA, for use as a transcript in protein synthesis, and pre-genomic RNA, for use as the template during genome replication . Virally encoded reverse transcriptase uses the pre-genomic RNA as a template for the creation of genomic DNA . </P>

The genetic material of retroviruses such as hiv is
