<P> Mitochondrial DNA ( mtDNA or mDNA ) is the DNA located in mitochondria , cellular organelles within eukaryotic cells that convert chemical energy from food into a form that cells can use , adenosine triphosphate ( ATP ) . Mitochondrial DNA is only a small portion of the DNA in a eukaryotic cell ; most of the DNA can be found in the cell nucleus and , in plants and algae , also in plastids such as chloroplasts . </P>
