Question

Which of the following pairs of organelles does not contain DNA?

• A. Nuclear envelope and mitochondria
• B. Mitochondria and lysosome
• C. Chloroplast and vacuoles
• D. Lysosomes and vacuoles

Answer 1

The correct option is D Lysosomes and vacuoles

Lysosomes are single membrane bound vesicular structures formed in the Golgi apparatus. They contain powerful hydrolytic enzymes. They do not contain any DNA.

Vacuole is the membrane-bound space found in the cytoplasm of a cell. In plant cells, vacuoles occupy 90% of the cell volume. DNA is absent in vacuoles.

DNA is present in the nucleus, mitochondria and chloroplasts. Hence, the first three options have at least one organelle with DNA, while option 'd' has none.
