Concept:Mitochondria contain their own DNA and ribosomes, which enable them to synthesize some of their own proteins independently.Explanation:Mitochondria are semi‑autonomous organelles with a circular DNA molecule and 70S ribosomes.These ribosomes are similar to those found in prokaryotes and allow the organelle to translate its own mRNA into proteins.Thus, mitochondria can produce a portion of the proteins required for their function, particularly those involved in oxidative phosphorylation.The presence of this protein‑synthesis machinery distinguishes mitochondria from most other organelles.
