Question

Mitochondria are considered semi-autonomous because:
Options
A They lack a membrane
B They don’t replicate
C They have their own DNA and ribosomes
Correct Answer
D They do not participate in metabolism
Correct Answer

Option C is the correct answer.

Detailed Explanation

Mitochondria possess their own genetic material (mtDNA) and protein-synthesis machinery (ribosomes), allowing them to produce some of their own proteins and replicate independently of the cell cycle, though they rely on the nucleus for most proteins.

Hint

They have some, but not all, genetic independence.
