Retro virus causing AIDS has which kind of genome?

Options

A. DNA
B. RNA
C. m-RNA
D. Proteins

Answer

To answer the question about the type of genome that the retrovirus causing AIDS has, we can follow these steps:

### Step-by-Step Solution:

1. **Identify the Virus**: The virus responsible for causing AIDS is known as HIV (Human Immunodeficiency Virus).

2. **Classify the Virus**: HIV is classified as a retrovirus. Retroviruses are a specific group of viruses that have unique characteristics in their genetic material.

3. **Determine the Genetic Material**: The genetic material of HIV is made up of RNA.

4. **Specify the Type of RNA**: The RNA present in HIV is single-stranded RNA (ssRNA). This means that the RNA consists of a single strand rather than the double-stranded structure found in DNA.

5. **Conversion Process**: When HIV infects a host cell, it uses an enzyme called reverse transcriptase to convert its RNA genome into DNA. This process is a defining feature of retroviruses.

6. **Conclusion**: Therefore, the genome of the retrovirus causing AIDS (HIV) is single-stranded RNA.

### Final Answer:
The retrovirus causing AIDS has a single-stranded RNA genome.
