Question 1 of 5
Why is mitochondrial DNA particularly susceptible to damage?
Correct Answer: D
Rationale: The correct answer is D because mitochondria are the main source of reactive oxygen species (ROS), which can damage DNA. Mitochondrial DNA is located near the electron transport chain where ROS are produced. This proximity increases the chances of oxidative damage to the mitochondrial DNA. Choices A, B, and C are incorrect because mitochondrial DNA polymerase does have some proof-reading activity, oxygen content is necessary for mitochondrial function, and mitochondrial DNA damage is not solely due to aging but also due to ROS production.
