Answer:
The virus that relies on molecules called reverse transcriptase to build DNA from its RNA molecules is RetroVirus.
Explanation:
Retrovirus is a type of virus that is made up of RNA. When it attacks a cell, RNA is inserted into the host cell. Retrovirus has a special enzyme called reverse transcriptase that is used to create DNA by using RNA as template. It inserts its RNA into host genome and changes the genetic information.
