Answer:
The DNA of mitochondria is used to make proteins needed for mitochondrial function.
Explanation:
The DNA in the mitochondria or the mtDNA is necessary for the proper functioning of mitochondria because the genes associated make proteins for a large enzyme Cytochrome oxidase complex called as Cytochrome C complex. Furthermore, there are these main reasons why mtDNA has a very high rate of mutation and is maternally inherited to conserved it's sequence and expression over next generations.
