Mitochondrial DNA is primarily involved in coding for proteins needed for electron transport. Therefore, in which body systems would you expect most mitochondrial gene mutations to be exhibited?
A) the immune system and the blood
B) the excretory and respiratory systems
C) the skin and senses
D) the nervous and muscular systems
E) the circulation system

Question

Mitochondrial DNA is primarily involved in coding for proteins needed for electron transport, which occurs in the mitochondria of cells. The nervous and muscular systems are heavily reliant on ATP produced by mitochondria and would therefore be the systems most affected by mitochondrial gene mutations.
