9th grade work 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.
Keeping some DNA needed by mitochondria in the cell's nucleus and some in the mitochondria itself provides several advantages. Firstly, the nucleus acts as a protective hub for the DNA, shielding it from potential damage in the mitochondria. This ensures the genetic material remains intact and functional. Secondly, having some DNA in the mitochondria enables it to rapidly synthesize proteins needed for its proper functioning without relying on the cell's nucleus. Lastly, this division of DNA allows for efficient regulation of gene expression, as different genes can be regulated separately in the nucleus and mitochondria, tailoring their activity to specific cellular needs.
