What (who) is mitochondrial DNA - definition


Mitochondrial DNA         
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, such as 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.

(Only a single branch defining marker, preferably from the coding region, is shown.) The main geographic features of haplogroup distribution are highlighted with colour.
HAPLOGROUP DEFINED BY DIFFERENCES IN HUMAN MITOCHONDRIAL DNA
Human mitochondrial DNA (mtDNA) haplogroup; Human mitochondrial DNA haplogroups; Human mitochondrial dna haplogroup; Mitochondrial DNA haplogroup; Mitochondrial DNA Haplogroup; Mt-DNA haplogroup; MtDNA haplogroup
In human genetics, a human mitochondrial DNA haplogroup is a haplogroup defined by differences in human mitochondrial DNA. Haplogroups are used to represent the major branch points on the mitochondrial phylogenetic tree.
Examples of use of mitochondrial DNA
1. The plan is to extract a sample of mitochondrial DNA.
2. The study involved mitochondrial DNA, called mtDNA, which is passed only through the mother.
3. About one in 5,000 people carry defects in the mitochondrial DNA.
4. For instance, Haak examined only DNA (the mitochondrial DNA) from the female line.
5. One unique feature of mitochondria is that they have their own DNA, known as mitochondrial DNA, which is inherited from the mother only.
