Glossary Term: Mitochondrial DNA

DNA (plural DNAs) found in mitochondria, which contain some structural genes and is generally inherited only through the female line. Mitochondrial DNA (mtDNA or mDNA) is the DNA located in organelles called mitochondria, structures within eukaryotic cells that convert chemical energy from food into a form that cells can use, adenosine triphosphate (ATP). Nearly all of the DNA present in eukaryotic cells can be found in the cell nucleus, and in plants, the chloroplast as well.
