Main source of energy for reactions that occur in all living organisms is ATP.
Answer:
They transcribe RNA to DNA using reverse transcriptase.
Explanation:
<u>Retrovirus</u>
A type of virus that uses RNA as its genetic material. After infecting a cell, a retrovirus uses an enzyme called reverse transcriptase to convert its RNA into DNA. The retrovirus then integrates its viral DNA into the DNA of the host cell, which allows the retrovirus to replicate. HIV, the virus that causes AIDS, is a retrovirus.
Retroviruses have an enzyme, called reverse transcriptase, that gives them the unique property of transcribing their RNA into DNA after entering a cell.
