Which of the following organelles contain DNA? (i) Mitochondria (ii) Chloroplasts (iii) Golgi bodies (iv) Ribosomes
Options:
Answer:
A
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.
