It is the mitochondria produces energy for the cell and has its own DNA.
Explanation:
Mitochondria is also called the power house of the cell. Mitodondria are membrane bound cell organelles that generate energy for cell biochemical reactions. It energy produced by mitochondria are stored in a small molecule of adenosine triphosphate(ATP). Mitochondria contain genetic material called mitochondrial DNA. The major function of mitochondria is cellular respiration I.e it takes in nutrients from the cells and break it down to release energy.
The mitochondria produces energy for the cell to use by converting chemical energy from food into a form of energy in which is usable to the host cell through a process of oxidative phosphorylation
Although DNA is mainly packaged within chromosones confined in the nucleus, mitochondria also has a small quantity of unique DNA found within them called mitochondrial DNA. DNA found within the mitochondria differs from DNA found within the nucleus in the sense that it can self replicate.
The answer is D. A mutation in sex cells. Sex cells are what affect offspring, so a mutation in the sex cell would most likely affect a person's offspring.
