Which one of the following has its own DNA ?

Options

A. Peroxisome
B. Mitochondria
C. Dictyosome
D. Lysosome

Answer

**Step-by-Step Solution:**

1. **Understanding the Question:**
The question asks which organelle has its own DNA among the given options: Peroxisome, Mitochondria, Dictyosome, and Lysosome.

2. **Analyzing Each Option:**
- **Peroxisome:** These are membrane-bound organelles involved in the oxidation of specific biomolecules and the biosynthesis of certain lipids. They do not contain their own DNA.
- **Mitochondria:** Known as the powerhouse of the cell, mitochondria generate most of the cell's chemical energy. Importantly, mitochondria contain their own DNA, which is distinct from the nuclear DNA found in the cell's nucleus.
- **Dictyosome:** This is part of the Golgi apparatus and is involved in the transfer of materials. It does not contain its own DNA.
- **Lysosome:** This organelle is responsible for digestion within the cell and contains various enzymes. It does not have its own DNA.

3. **Identifying the Correct Answer:**
After analyzing all the options, it is clear that the only organelle that has its own DNA is **Mitochondria**.

4. **Conclusion:**
Therefore, the answer to the question "Which one of the following has its own DNA?" is **Mitochondria**.
