Answer: RETROVIRUSES
Step-by-step explanation:
A Retrovirus, a type of virus from the viral family Retroviridae., is a virus whose genes are encoded in their single stranded RNA which serves as a basis for DNA synthesis This iRNA then makes copies of itself by first coding its genes reversely into the DNA of the cells it infects using an enzyme called reverse transcriptase,
Like other viruses, retroviruses attach through the cell of the organisms they infect to replicate themselves,but are different from viruses by reverse transcription and genome integration
There are three Retroviruses that can affect humans which are HIV,Human T-cell lymphotropic virus (HTLV) types 1 and 2 and the flow chart of their life cycle to illustrate how retroviruses replicate is given below by
