Question
Which statement is NOT correct when comparing mitocondria with the nucleus and the role DNA plays for both organelles.
mitochondria are smaller than nuclei and contain enzymes required for energy production
the nucleus is the genetic storage organelle, protecting DNA from damage
all the DNA material in a cell remains in the nucleus
mitochondria need to keep some DNA to replicate independently of the cell to provide energy for the cell division process

The statement that is NOT correct is:
**"all the DNA material in a cell remains in the nucleus."**
This statement is inaccurate because, while the nucleus contains the majority of the cell's genetic material (nuclear DNA), mitochondria also contain their own DNA (mtDNA). This mitochondrial DNA is separate from the nuclear DNA and is involved in the coding of certain proteins necessary for mitochondrial function and energy production.

Yes, I am sure. To clarify further:
1. The nucleus is indeed the main storage site for the cell's genetic material (nuclear DNA), and it plays a crucial role in protecting that DNA and regulating gene expression.
2. Mitochondria have their own DNA (mtDNA), which is separate from nuclear DNA. This mtDNA is essential for the mitochondria's function, particularly in energy production.
3. The statement "all the DNA material in a cell remains in the nucleus" is incorrect because it overlooks the presence of mitochondrial DNA.
