Which virus possesses two RNA genomes ?

Options

A. TMV
B. Potato Mosaic virus
C. HIV
D. Rotavirus

Answer

To determine which virus possesses two RNA genomes, we can follow these steps:

### Step 1: Understand the Question
We need to identify a virus that has two RNA genomes. This means we are looking for a virus that contains two copies of RNA within its structure.

### Step 2: Review the Options
The options provided are:
- TMV (Tobacco Mosaic Virus)
- Potato Mosaic Virus
- HIV (Human Immunodeficiency Virus)
- Rotavirus

### Step 3: Analyze Each Virus
1. **TMV (Tobacco Mosaic Virus)**: This virus has a single-stranded RNA genome. It does not possess two RNA genomes.

2. **Potato Mosaic Virus**: Similar to TMV, this virus also has a single-stranded RNA genome. It does not have two RNA genomes.

3. **HIV (Human Immunodeficiency Virus)**: HIV is classified as a retrovirus and is known to have two copies of RNA in each virus particle. This means it possesses two RNA genomes.

4. **Rotavirus**: This virus has a double-stranded RNA genome but does not have two separate RNA genomes.

### Step 4: Conclusion
After analyzing the options, the only virus that possesses two RNA genomes is **HIV (Human Immunodeficiency Virus)**.

### Final Answer
The virus that possesses two RNA genomes is **HIV (Human Immunodeficiency Virus)**.
