Question

HIV is a

• A. DNA virus
• B. RNA virus
• C. Paramyxo virus
• D. Retrovirus

Hint:

Retroviruses, like HIV, have RNA genomes that are reverse transcribed into DNA once inside host cells.

Answer 1

The Correct Option is D

Step 1: Understanding HIV.
HIV (Human Immunodeficiency Virus) is a retrovirus. Retroviruses are RNA viruses that use reverse transcription to convert their RNA genome into DNA once inside a host cell. This DNA then integrates into the host cell's genome.
Step 2: Analyzing the options.
(A) DNA virus: This is incorrect as HIV is an RNA virus, not a DNA virus.
(B) RNA virus: While HIV is an RNA virus, it is specifically a retrovirus, which is a subclass of RNA viruses.
(C) Paramyxo virus: Paramyxoviruses are a different group of RNA viruses, unrelated to HIV.
(D) Retrovirus: Correct — HIV is a retrovirus, which is a type of RNA virus that replicates by reverse transcription.
Step 3: Conclusion.
The correct answer is (D) Retrovirus as HIV is a retrovirus.
