Question

What are retro viruses?

Answer 1

Explanation:

A retrovirus is a type of RNA virus that inserts a copy of its genome into the DNA of a host cell that it invades, thus changing the genome of that cell.

Answer 2

Retrovirus:

●A virus that is composed not of DNA but of RNA.

● Retroviruses have an enzyme, called reverse transcriptase, that gives them the unique property of transcribing their RNA into DNA after entering a cell.

●The retroviral DNA can then integrate into the chromosomal DNA of the host cell, to be expressed there.
