n 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 several advantages. Firstly, having some DNA in the nucleus allows for greater control and regulation over the mitochondrial activities. It enables the cell to regulate the production and maintenance of mitochondrial DNA, ensuring the optimal functioning of mitochondria. Furthermore, in case of any damage or mutations in the mitochondrial DNA, having backup copies in the nucleus safeguards against complete loss of crucial genetic information. Lastly, this distribution of DNA helps in the process of mitochondrial biogenesis, where both the nucleus and mitochondria coordinate the synthesis of mitochondrial components, ensuring efficient and coordinated functioning of the organelle.
