Influenza virus has

Options

A. DNA
B. RNA
C. Both (a) and (b)
D. Only proteins and no nucleic acids

Explanation

**Step-by-Step Solution:**

1. **Identify the Virus**: The question asks about the influenza virus, which is known to cause respiratory infections in humans.

2. **Determine the Genetic Material**: The influenza virus contains genetic material that is crucial for its replication and function.

3. **Recognize the Type of Genetic Material**: The influenza virus has an RNA genome. This means that its genetic information is stored in ribonucleic acid (RNA) rather than deoxyribonucleic acid (DNA).

4. **Understand the Structure**: The RNA genome of the influenza virus is enclosed within a protective protein coat called a capsid. The influenza virus is unique in that it has eight segments of RNA.

5. **Role of RNA**: The RNA in the influenza virus serves as a template for synthesizing messenger RNA (mRNA). This process is essential for producing proteins that the virus needs to replicate.

6. **Enzymatic Action**: The synthesis of mRNA from the RNA genome is facilitated by an enzyme known as viral transcriptase (or reverse transcriptase). This enzyme helps convert the RNA into DNA first, which is then used to synthesize mRNA.

7. **Conclusion**: Based on the information gathered, the correct answer to the question "Influenza virus has" is that it has RNA as its genetic material.

**Final Answer**: The influenza virus has RNA as its genetic material.
