which statement is not correct when comparing mitochondria with the nucleus and the role DNA plays for both organelles.

Question

mitochondria are smaller than nuclei and contain enxymes 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 divison process

Answer 1

The statement that is not correct is:

"all the DNA material in a cell remains in the nucleus."

This statement is inaccurate because mitochondria also contain their own DNA (mtDNA), which is separate from the nuclear DNA. Mitochondrial DNA is involved in encoding some of the proteins needed for mitochondrial function and energy production. Therefore, not all DNA in a cell is contained within the nucleus; some is located in the mitochondria.
