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.

explanation:

the relative atomic mass of an element is the mass of one atom of that element, relative to 1/12th of the mass of a  1212c atom. to convert to an absolute mass in kg, it is necessary to multiply by  1.661×10−271.661×10−27.

the relative atomic mass is roughly equal to the number of neutrons, plus the number of protons, in the nucleus of the atom.

for elements with more than one stable isotope (different types of nucleus with different numbers of neutrons but the same number of protons), the quoted mass is usually the average mass, weighted by the relative abundance of the different isotopes.
