Assertion : Mitochondria and chloroplasts have their own genome.
Reason : Endoplasmic reticulum and Golgi body are the cell organelles which have their own DNA.
Options

- BIf both assertion and reason are true but reason is not the correct explanation of assertion.
- CIf assertion is true but reason is false
- DIf both assertion and reason are false
Correct answer
C. If assertion is true but reason is false
Step-by-step solution
Both mitochondria and chloroplast are semi-autonomous organelles as they possess their own DNA, RNA and 70S 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.
