Which of the following cellular organelles contains its own circular DNA molecules, seventy-S ribosomes, and replicates independently through binary fission inside eukaryotic cells?

💡 Solution & Explanation

Mitochondria possess their own circular DNA and prokaryotic-like seventy-S ribosomes, supporting the endosymbiotic theory which proposes that mitochondria evolved from engulfed aerobic bacteria. Golgi apparatus, lysosomes, and endoplasmic reticulum lack independent genomes and are synthesized under nuclear genetic control. Mitochondrial DNA is inherited maternally in most multicellular organisms.
