Circular and double stranded DNA occurs in -

Options

A. Golgibody
B. Mitochondria
C. Nucleus
D. Cytoplasm

Answer

To solve the question "Circular and double stranded DNA occurs in -", we can follow these steps:

### Step 1: Understand the Structure of DNA
- DNA (deoxyribonucleic acid) can be found in different forms in various organisms. It is typically linear in eukaryotic cells and circular in prokaryotic cells.

### Step 2: Identify the Options
- The options provided are:
1. Golgi body
2. Mitochondria
3. Nucleus
4. Cytoplasm

### Step 3: Analyze Each Option
- **Golgi Body**: This organelle is involved in modifying, sorting, and packaging proteins and lipids. It does not contain DNA.

- **Mitochondria**: These are organelles found in eukaryotic cells that are responsible for energy production. They contain their own DNA, which is circular and double-stranded, similar to prokaryotic DNA.

- **Nucleus**: The nucleus contains linear DNA organized into chromosomes. It does not contain circular DNA.

- **Cytoplasm**: This is the fluid inside the cell where various organelles are suspended. It does not contain DNA.

### Step 4: Conclusion
- Based on the analysis, the only option that contains circular and double-stranded DNA is **Mitochondria**.

### Final Answer
- Circular and double-stranded DNA occurs in **Mitochondria**.
