Question [CLICK ON ANY CHOICE TO KNOW THE RIGHT ANSWER]
both the chloroplast and mitochondria have DNA
A
true
B
false
C
Either A or B
D
None of the above
Explanation: 

Detailed explanation-1: -Both the mitochondria and the chloroplasts have their own DNA and divide on their own by simple fission, just by splitting into two and partitioned between the daughter cells produced by mitosis. Q. Assertion: Mitochondria and chloroplast are semi-autonomous cells organelles.

Detailed explanation-2: -Answer and Explanation: The statement is TRUE. Both chloroplasts and mitochondria contain their own sets of DNA which are circular and known as extranuclear DNA or DNA that does not come from the eukaryotic cell’s nucleus.

Detailed explanation-3: -Both chloroplasts and mitochondria function to generate metabolic energy, evolved by endosymbiosis, contain their own genetic systems, and replicate by division. However, chloroplasts are larger and more complex than mitochondria, and they perform several critical tasks in addition to the generation of ATP.

Detailed explanation-4: -Both mitochondria and chloroplasts have their own DNA as mitochondrial DNA and chloroplast DNA. Moreover, both types of DNA are double-stranded circular DNA which occurs in multiple copies. Compared to mitochondrial DNA, chloroplast DNA is large in size and contains more genes.
