Which one contains DNA (i) Mitochondria (ii) Chloroplasts (iii) Golgi bodies (iv) Ribosomes

Options

A. I and II
B. ii and iii
C. I only
D. iv only

Answer

To solve the question "Which one contains DNA?" from the options provided: (i) Mitochondria (ii) Chloroplasts (iii) Golgi bodies (iv) Ribosomes, we can follow these steps:

### Step-by-Step Solution:

1. **Identify the Organelles**:
- We have four organelles to consider: Mitochondria, Chloroplasts, Golgi bodies, and Ribosomes.

2. **Analyze Mitochondria**:
- Mitochondria are known as the powerhouse of the cell. They are involved in ATP production and are considered semi-autonomous organelles.
- **Key Point**: Mitochondria contain their own DNA, which is circular in nature.

3. **Analyze Chloroplasts**:
- Chloroplasts are found in plant cells and are responsible for photosynthesis. Like mitochondria, they are also semi-autonomous.
- **Key Point**: Chloroplasts also contain their own DNA, which is circular.

4. **Analyze Golgi Bodies**:
- Golgi bodies are involved in the sorting, packaging, and transport of proteins. They are membrane-bound organelles.
- **Key Point**: Golgi bodies do not contain their own DNA.

5. **Analyze Ribosomes**:
- Ribosomes are the sites of protein synthesis and are found in both prokaryotic and eukaryotic cells.
- **Key Point**: Ribosomes do not contain their own DNA.

6. **Conclusion**:
- From the analysis, we find that both mitochondria and chloroplasts contain DNA, while Golgi bodies and ribosomes do not. Therefore, the correct answers are (i) Mitochondria and (ii) Chloroplasts.

### Final Answer:
Mitochondria and Chloroplasts contain DNA.
