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)Excretory and respiratory systems
C)The skin and senses
D)Nervous and muscular systems
E)Circulation

Question
