Which organelle in the cell, other than nucleus, contains DNA?
- ACentriole
- BGolgi apparatus
- CLysosome
- DMitochondrionCorrect
Explanation
The correct answer is mitochondrion because it is one of the few organelles that possesses its own independent genetic material, known as mitochondrial DNA. According to the endosymbiotic theory, mitochondria were once free living prokaryotic organisms that entered into a symbiotic relationship with eukaryotic cells. This allows mitochondria to produce some of their own proteins and replicate independently of the cell cycle. While the nucleus holds the majority of a cells DNA, mitochondria and chloroplasts in plants are the only other organelles that contain their own DNA. Centrioles, the Golgi apparatus, and lysosomes do not contain DNA.
