Mitochondria, often called the powerhouse of the cell, are organelles in eukaryotic cells that contain their own genetic material in the form of circular DNA.

Eukaryotic cells have their primary DNA located in the nucleus. However, mitochondria (in animals, fungi, and plants) and chloroplasts (in plants and algae) also contain their own distinct DNA.

The presence of DNA in mitochondria and chloroplasts supports the endosymbiotic theory, which suggests that these organelles originated from free-living prokaryotic organisms that were engulfed by ancestral eukaryotic cells. Lysosomes, Golgi apparatus, and Endoplasmic reticulum are other eukaryotic organelles but do not possess their own DNA.
