Among the following, which cellular organelle contains circular DNA, similar to those found in bacteria?
Correct answer: D. Mitochondria
- A. Lysosome
- B. Nucleus
- C. Nucleosome
- D. Mitochondria
Explanation
Chloroplasts and mitochondria are the two organelles, that contain circular DNA similar, to those found in prokaryotic cells, along with 70S ribosomes, which are also similar to the ones in prokaryotes, such as in bacteria. This can be traced back to the endosymbiotic theory, where mitochondria and chloroplasts are understood to be ancient prokaryotes.
