Ecole Polytechnique Fédérale de Lausanne Apr 2 2026 Mitochondria are often described as the cell's power plants, because they generate energy. To help them achieve this, mitochondria carry their own small genome called mitochondrial DNA (mtDNA). Each cell contains hundreds to thousands of copies of mtDNA, packaged into clusters known as nucleoids. Scientists have known that nucleoids are regularly spaced inside mitochondria. This pattern ensures that mtDNA is passed down when cells divide and
