Question

Mitochondria and chloroplast are;

• A. Semi-autonomous organelles
• B. Formed by division of pre-existing organelles and they contain DNA but lack protein synthesizing machinery
• C. Extranuclear
  
• D. Both A and B
  

Answer 1

The correct option is D Both A and B

Mitochondria and chloroplast are semi-autonomous organelles. They are capable of self duplication. For duplication they have circular double stranded DNA, 70S ribosomes and different types of RNA's that is mRNA, tRNA, rRNA for protein synthesis.

Formed by division of pre-existing organelles and they contain DNA and protein synthesizing machinery.

They are present outside the nucleus so they are extranuclear.

So, the correct answer is 'Both A and B'.
