Question

Organelle other than nucleus, containing DNA is

• A. Endoplasmic reticulum
• B. Golgi apparatus
• C. Mitochondria
• D. Lysosome

Answer 1

The correct option is C

Mitochondria

The correct option is option C.

Explanation of correct option:

1. Other than the nucleus, the mitochondria are the organelles that contain DNA.
2. In contrast to chromosomal DNA, the mitochondria contain nucleic material known as mitochondrial DNA.
3. This mitochondrial DNA has been preserved for centuries without being destroyed.
4. Mitochondrial DNA is employed in phylogenetic analyses.

Explanation of incorrect option:

Option A:

1. The endoplasmic reticulum is the eukaryotic cell's transportation system, as well as a host of other activities such as protein folding.

Option B:

1. Golgi Apparatus packages proteins into membrane-bound vesicles inside the cell before they are delivered to their destination, and it is part of the endomembrane system in the cytoplasm.

Option D:

1. Lysosomes are membrane-enclosed organelles that contain a variety of enzymes that can degrade a wide range of biological polymers, including proteins, nucleic acids, carbohydrates, and lipids.

Final answer: Organelle other than nucleus, containing DNA is mitochondria.
