A retrovirus enters the host cell, then it uses an enzyme called reverse transcriptase to produce DNA from its RNA sequence
-the DNA from the retrovirus is then added to the host cell genome, by an enzyme called integrase
-the retrovirus then continues to infect host cells and add genetic material to them; this is why the retroviruses are useful in biotechnology to deliver genes
-also, the retrovirus is created in such a way that it does not cause disease or destroy host cells
-the scientists using the retroviruses also most likely ensure that the retrovirus cannot spread through air, to make it less contagious
-however, transferring infected host cells to an organism not infected by the retrovirus, for example, by contact with bodily fluids, most likely will spread the retrovirus
-once scientists used a retrovirus to transfer genes for resistance to HIV from rhesus monkeys to cats, and also added genes for florescent proteins to the retrovirus, to show that the retrovirus had inserted the genes into the host cells.

Answer:
any of a group of RNA viruses which insert a DNA copy of their genome into the host cell in order to replicate,
