Q1. A cell biologist notes that mitochondria can increase in number within a cell. Which structural feature directly supports their self-replicating ability?
Answer: Presence of circular DNA
Explanation: Mitochondria possess their own DNA and ribosomes, allowing them to self-replicate independently of the main cell cycle.
