Question

Which one of the group of cell organelles possess their own DNA ?

• A. Nucleus, ribosome, lysosome
• B. Chloroplast, mitochondria, ribosome
• C. Nucleus, nucleolus, ribosome
• D. Nucleus, mitochondria, chloroplast

Answer 1

The correct option is D Nucleus, mitochondria, chloroplast

Cell organelles like the nucleus, chloroplast and mitochondria have their own DNA. These organelles have the double membrane. Nuclear DNA is linear and double-stranded while DNA of mitochondria and chloroplast is circular and double-stranded. Due to the presence of DNA, these organelles are also called as semiautonomous cell organelles. Ribosomes are made up of proteins and RNA. Lysosomes possess digestive enzyme which helps in intracellular digestion. However, lysosome and ribosome lack DNA.

Thus, the correct answer is option D.
