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).
Mitochondria carry their own separate DNA (mtDNA) that is independent of the nuclear DNA of the same cell. Human mtDNA is composed of 37 genes totaling about 16,000 base pairs. This mtDNA also mutates at a much faster rate than nuclear DNA (nucDNA) does.ince there were no DNA changes due to genetic recombination events (ie: with paternal DNA-now known to be a wrong assumption), they assumed that all changes in the mtDNA were the result of mutations over time and that these mutations occurred at a constant rate.
