Question

Why do mitochondria require nuclear-encoded proteins despite having their own DNA?

Accepted Answer

Their DNA does not encode all the proteins necessary for mitochondrial function.

Their DNA is only used for replication, not protein synthesis.

Answer

Their ribosomes are incapable of synthesizing proteins.

Answer

Their DNA is identical to nuclear DNA, making it redundant.
