In three to five sentences, explain the advantage of keeping some DNA needed by mitochondria in the cell’s nucleus and some in the mitochondria itself.(4 points)

Answer 1

Keeping some DNA needed by mitochondria in the cell's nucleus and some in the mitochondria itself provides certain advantages. Firstly, having a portion of the mitochondrial DNA in the nucleus allows for efficient repair of damaged DNA, as the nucleus is protected by a nuclear membrane. Secondly, by having some mitochondrial DNA in the mitochondria itself, it ensures the production of essential proteins within the organelle. Additionally, having a small portion of the mitochondrial DNA in the nucleus allows for a regulated control of mitochondrial functions by the cell. Lastly, this distribution of DNA in both locations helps prevent mutations from spreading throughout the entire mitochondrial genome.
