Choose the correct answers from the alternatives given :
Extranuclear chromosomes occur within various organelles, including:

• A. lysosomes
• B. chloroplasts
• C. endoplasmic reticulum
• D. all of these

Answer 1

The correct option is B chloroplasts

Initially, it was thought that entire genetic information resided in the nuclear DNA. Later it was found that mitochondria and chloroplast possessed its own genetic machinery. The genetic material present outside of the nucleus is called extranuclear chromosomes. Due to the presence of extranuclear chromosomes, they both are also called semi-autonomous organelles.

So, the correct option is 'chloroplasts'.
