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)
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.
