Mitochondrial Chromosomes: Mitochondria are tiny structures inside cells that synthesize molecules used for energy. Unlike other structures inside cells, each mitochondrion contains its own circular chromosome. This chromosome contains DNA (mitochondrial DNA) that codes for some, but not all, of the proteins that make up that mitochondrion. Mitochondrial DNA usually comes only from the person's mother because, in general, when an egg is fertilized, only mitochondria from the egg become part of the developing embryo. Mitochondria from the sperm usually do not become part of the developing embryo.
