Genetic material in animal viruses like influenza virus, polio virus, measles virus and HIV is

Options

A. (a) ssRNA
B. (b) ssDNA
C. (c) dsDNA
D. (d) dsRNA

Answer

To determine the genetic material in animal viruses like influenza virus, polio virus, measles virus, and HIV, we can follow these steps:

### Step-by-Step Solution:

1. **Identify the Viruses**: Start by recognizing the viruses mentioned in the question: influenza virus, polio virus, measles virus, and HIV.

2. **Research Virus Classification**: Understand that viruses can be classified based on their genetic material, which can be either DNA or RNA. They can also be single-stranded (ss) or double-stranded (ds).

3. **Analyze Each Virus**:
- **Influenza Virus**: This is known to have RNA as its genetic material.
- **Polio Virus**: This virus also contains RNA.
- **Measles Virus**: Similarly, measles virus has RNA as its genetic material.
- **HIV**: The Human Immunodeficiency Virus is known to have RNA as its genetic material.

4. **Determine the Type of RNA**: Next, we need to identify whether the RNA in these viruses is single-stranded or double-stranded.
- All the viruses mentioned (influenza, polio, measles, and HIV) have single-stranded RNA (ssRNA).

5. **Conclusion**: Based on the analysis, we conclude that the genetic material in these animal viruses is single-stranded RNA (ssRNA).

### Final Answer:
The genetic material in animal viruses like influenza virus, polio virus, measles virus, and HIV is **single-stranded RNA (ssRNA)**.
