ssDNA is genetic material is found in

Options

A. `phixx174` coliphage
B. `T_(2)` coliphage
C. influenza virus
D. wound Tumor virus

Answer

To determine where single-stranded DNA (ssDNA) is found as genetic material, we will analyze each option provided in the question step by step.

### Step-by-Step Solution:

1. **Understanding the Question**: The question asks which organism or virus has single-stranded DNA as its genetic material.

2. **Evaluating Option A - 5 to 174 Coliphage**:
- The 5 to 174 coliphage is known to have circular single-stranded DNA as its genetic material.
- It consists of approximately 5,386 nucleotides and encodes for 11 proteins.
- Therefore, this option is a valid answer as it contains ssDNA.

3. **Evaluating Option B - T2 Coliphage**:
- The T2 coliphage is known to have double-stranded DNA (dsDNA) as its genetic material.
- Since the question specifically asks for ssDNA, this option is incorrect.

4. **Evaluating Option C - Influenza Virus**:
- The influenza virus does not use DNA as its genetic material; instead, it uses single-stranded RNA (ssRNA).
- Therefore, this option is also incorrect.

5. **Evaluating Option D - Wound Tumor Virus**:
- The wound tumor virus primarily uses RNA as its genetic material, not DNA.
- Hence, this option is incorrect as well.

6. **Conclusion**: After evaluating all the options, the only correct answer is **Option A - 5 to 174 Coliphage**, which has single-stranded DNA as its genetic material.

### Final Answer:
**The correct answer is 5 to 174 Coliphage.**
