Mitochondrial Dna
Mitochondrial DNA (mtDNA) is a type of DNA located in the mitochondria of human cells. It is a circular double-stranded DNA molecule, and is distinct from the nuclear DNA found in the nucleus of the cell. This type of DNA is inherited only from the mother, and is used to study the maternal line of a family and ancestry. mtDNA has been used to map out human migration and population movements, and has also been used to test the relatedness of individuals and species. Additionally, mtDNA mutations can be used to identify inherited diseases or illness, and this type of DNA is often used for forensic analysis.
