Question

In four to five sentences, explain the advantage of keeping some DNA needed by mitochondria in the cell’s nucleus and some in the mitochondria itself. Please make your answer simple, yet coherent, and intended for 9th grade.

Answer 1

Mitochondria have their own DNA, which is important for producing energy in cells. However, having some mitochondrial DNA in the cell's nucleus helps protect it from damage and ensures that it can be more easily copied and passed on during cell division. This arrangement allows the cell to have better control over mitochondrial functions and makes it easier to fix any problems if the mitochondria start to malfunction. Overall, this combination helps cells work efficiently and stay healthy.
