DNA Testing Glossary
- Mitochondrial DNA
- Mitochondria are often referred to as cellular power supplies or batteries, as the primary function of mitochondria is to regulate cellular energy functions. Mitochondria contain DNA, and mitochondrial DNA has its own genome, unique from the cell’s nuclear DNA genome. All mitochondrial DNA in humans (both male and female) is inherited from the mother. Mitochondrial DNA is particularly useful in making determinations about maternal or female bloodlines.
