Help me check my answer! And rephrase if needed 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.

A. A higher copy number, a lack of sequence ambiguities from heterozygous genotypes, and a faster rate of mutation are all useful for species identification.
Thus, the benefits of storing some of the DNA required by mitochondria in the cell's nucleus and some in the mitochondria themselves are discussed above.

Mitochondria is the cell organelle that produced the energy that is needed in the body system in form of atp, that is why it is called the power house of the cell. energy is needed by the living organisms to carry out the activities which sustain life.  if the mitochondria is destroyed atp will not be produced. if the mitochondria is destroyed, energy production will stop and the affected living organism will not have the energy to carry out the necessary life processes; this will lead to the death of the organism.

The answer is lymph sinuses.
