Official UPSC Answer KeyUPSC Prelims 2001 • Science and Technology

Correct Answer: Option (D) — Mitochondrion

Concept & Option Breakdown

Standard Reference Verified
  • Mitochondrion (along with chloroplasts in plants) contains its own circular DNA molecule (mtDNA) and ribosomes, enabling it to synthesize some of its own proteins (semi-autonomous organelle according to endosymbiotic theory).
  • Centrioles, Golgi apparatus, and Lysosomes do not contain DNA.
Elimination Heuristic & Exam Approach

Endosymbiotic organelles—mitochondria and chloroplasts—are the only cellular organelles outside the nucleus that have their own autonomous genetic material (DNA).
