Nuclear DNA of Amoeba is

Options

A. single stranded
B. double helix
C. circular
D. like a clover leaf

Answer

To answer the question regarding the nuclear DNA of Amoeba, we can follow these steps:

### Step-by-Step Solution:

1. **Understand the Structure of DNA**:
- DNA (Deoxyribonucleic Acid) can exist in various forms. The most common forms are single-stranded and double-stranded.

2. **Identify the Types of Organisms**:
- Single-stranded DNA is typically found in viruses.
- Double-stranded DNA is characteristic of eukaryotic organisms, which include Amoeba.
- Circular DNA is primarily found in prokaryotes, such as bacteria.
- Cloverleaf structure is associated with tRNA, not DNA.

3. **Analyze the Options**:
- **Single-stranded**: Incorrect, as this is not typical for eukaryotic organisms.
- **Double helix**: Correct, as eukaryotic organisms, including Amoeba, have double-stranded DNA.
- **Circular**: Incorrect, as this is characteristic of prokaryotic DNA.
- **Cloverleaf**: Incorrect, as this structure pertains to tRNA, not DNA.

4. **Conclusion**:
- Based on the analysis, the nuclear DNA of Amoeba is **double helix**.

### Final Answer:
The nuclear DNA of Amoeba is **double helix**.
