Q: 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.

Mitochondrial DNA (mtDNA) has several advantages over nuclear DNA, including a higher copy number, a lack of sequence ambiguities from heterozygous genotypes, and a faster rate of mutation.
