Retroviruses are characterized by:
Correct answer: C. Reverse transcriptase enzyme
- A. Lack envelope
- B. Have no capsid
- C. Reverse transcriptase enzyme
- D. DNA genome
Explanation
Retroviruses are a unique group of RNA viruses that can reverse transcribe their RNA genome into DNA; that's how they are characterised. They are enveloped viruses and have a capsid.

About Acellular Life
Viruses are acellular infectious particles whose capsid, nucleic acid and host-dependent replication distinguish them from living cells. HIV infection covers transmission, replication, effects on helper T cells, progression to AIDS, symptoms, prevention and treatment, while AIDS is the disease state caused by advanced immune-system damage rather than a separate virus.
