Extranuclear DNA is found in :-

Options

A. Lysosome and chloroplast
B. Chloroplastand mitochondria
C. Mitochondria and lysosome
D. Gogli and E.R

Answer

**Step-by-Step Solution:**

1. **Understanding Extranuclear DNA**: Extranuclear DNA refers to genetic material that is not located within the nucleus of a cell. This type of DNA is typically found in specific organelles within eukaryotic cells.

2. **Identifying Eukaryotic Cells**: Eukaryotic cells are characterized by having a defined nucleus and various organelles. In these cells, apart from the nuclear DNA, there are organelles that contain their own DNA.

3. **Locating Extranuclear DNA**: The two main organelles that contain extranuclear DNA are:
- **Mitochondria**: Known as the powerhouse of the cell, mitochondria have their own DNA, which is involved in the production of ATP (adenosine triphosphate), the energy currency of the cell.
- **Chloroplasts**: Found in plant cells, chloroplasts are responsible for photosynthesis and also contain their own DNA.

4. **Conclusion**: Based on the information gathered, we can conclude that extranuclear DNA is found in both mitochondria and chloroplasts. Therefore, the correct answer to the question is that extranuclear DNA is found in these organelles.

5. **Final Answer**: The correct option is B: Chloroplast and Mitochondria.
