Question

RNA virus generally replicates in:

• A. Cytoplasm
• B. Nucleus
• C. Mitochondria
• D. Late endosomes

Hint:

RNA Virus = Cytoplasm (usually). DNA Virus = Nucleus (usually).

Answer 1

The Correct Option is A

Step 1: Concept
The intracellular site of viral replication is generally determined by the type of viral genome.

Step 2: Meaning
Most DNA viruses replicate in the nucleus, whereas most RNA viruses do not need nuclear machinery for RNA synthesis.

Step 3: Analysis
Most RNA viruses (except for Orthomyxoviruses like Influenza and Retroviruses) carry out their entire replication cycle in the host cell cytoplasm. This allows them to stay near the ribosomes for immediate translation.

Step 4: Conclusion
The cytoplasm is the typical site for RNA virus replication. Final Answer: (A)
