Question

Which of the following cell organelle does not contain DNA?

• A. Mitochondria
• B. Nucleus
• C. Chloroplast
• D. Lysosome

Hint:

Mitochondria and chloroplasts are unique organelles that contain their own DNA, whereas lysosomes do not.

Answer 1

The Correct Option is D

The cell organelles that contain DNA are mitochondria and chloroplasts. These organelles have their own DNA, separate from the DNA found in the nucleus, which is the control center of the cell. Lysosomes, on the other hand, do not contain any DNA.

Step 1: Define the organelles.
- Mitochondria and Chloroplasts both contain DNA, which is essential for their function and replication. They have their own genetic material, which is why they are sometimes referred to as semi-autonomous organelles.
- Lysosomes are involved in cellular digestion but do not have any DNA, as they are membrane-bound vesicles that contain enzymes for breaking down waste materials.


Step 2: Conclusion.
Thus, the organelle that does not contain DNA is the lysosome.

Final Answer: Lysosome.
