The cell organelle which has DNA is

Options

A. Endoplasmic reticulum
B. Golgi complex
C. Lysosome
D. Mitochondria

Answer

To answer the question "The cell organelle which has DNA is," we will analyze the options provided and identify the correct organelle that contains DNA.

### Step-by-Step Solution:

1. **Understand the Question**: The question asks for a cell organelle that contains DNA. DNA is the genetic material found in cells.

2. **Evaluate the Options**:
- **Option 1: Endoplasmic Reticulum (ER)**:
- The endoplasmic reticulum has two types: rough ER and smooth ER.
- Rough ER is involved in protein synthesis, while smooth ER is involved in lipid synthesis.
- **Conclusion**: ER does not contain DNA.

- **Option 2: Golgi Complex**:
- The Golgi complex is responsible for sorting and packaging proteins.
- **Conclusion**: The Golgi complex does not contain DNA.

- **Option 3: Lysosome**:
- Lysosomes are known as "suicidal bags" because they break down large molecules and remove worn-out cell parts.
- **Conclusion**: Lysosomes do not contain DNA.

- **Option 4: Mitochondria**:
- Mitochondria are known as the powerhouse of the cell and are involved in energy production.
- Importantly, mitochondria have their own DNA (mtDNA), which is separate from the nuclear DNA found in the cell nucleus.
- **Conclusion**: Mitochondria contain DNA.

3. **Final Answer**: Based on the evaluation of all options, the correct answer is **Mitochondria** (Option 4).
