Which of the following organelles have their own DNA and ribosomes?

Options

  1. AEndoplasmic reticulum and Golgi bodies
  2. BMitochondria and Chloroplast
  3. CEndoplasmic reticulum and cytoskeleton
  4. DCell wall and nucleolus

Correct 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
