- B. Mitochondria and Chloroplast
- C. Endoplasmic reticulum and cytoskeleton
- D. Cell wall and nucleolus
Answer
B. Mitochondria and Chloroplast
Step-by-step solution
Mitochondria and chloroplasts are semi-autonomous cell organelles. They possess their own circular, double-stranded DNA and 70S ribosomes, which allow them to synthesize some of their own proteins. Other organelles like the endoplasmic reticulum, Golgi bodies, cytoskeleton, and nucleolus do not contain their own DNA. Answer: Mitochondria and Chloroplast
