Q5 / 180 · AIIMS 2013 · Botany

Which of the following organelles contain DNA? (i) Mitochondria (ii) Chloroplasts (iii) Golgi bodies (iv) Ribosomes

  • Correct answer
    A
    (i) and (ii)
  • B
    (ii) and (iii)
  • C
    (i) only
  • D
    (iv) only.

Solution

Both mitochondria and chloroplast are semi-autonomous organelles as they possess their own DNA, RNA and 70 S ribosomes to have sufficient functional independence from cellular machinery. Chloroplasts DNA is bigger than mitochondrial DNA. However, genetic information contained in these DNAs is limited. DNA is naked (without histone proteins) in both.

Hence, the correct answer is option: 'A'.
