Mycophages have :

Options

A. ssRNA
B. ds RNA
C. ds DNA
D. ssDNA

Answer

To solve the question "Mycophages have:", we need to analyze the options provided and determine which type of nucleic acid is associated with mycophages.

### Step-by-Step Solution:

1. **Understanding Mycophages**:
- Mycophages are also known as mycoviruses. They are viruses that specifically infect fungi.

2. **Evaluating the Options**:
- **Option 1: Single-stranded RNA**:
- This option is incorrect. While some viruses have single-stranded RNA, mycophages predominantly do not fall into this category.

- **Option 2: Double-stranded RNA**:
- This option is correct. Most mycoviruses are known to have double-stranded RNA as their genetic material.

- **Option 3: Double-stranded DNA**:
- This option is incorrect. Mycophages do not typically have double-stranded DNA.

- **Option 4: Single-stranded DNA**:
- This option is also incorrect. Mycophages do not have single-stranded DNA.

3. **Conclusion**:
- After evaluating all the options, the correct answer is **Option 2: Double-stranded RNA**.

### Final Answer:
Mycophages have **double-stranded RNA**.
