1. 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. Human mitochondrial DNA was the first significant part of the human genome to be sequenced. This sequencing revealed that the human mtDNA includes 16,569 base pairs and encodes 13 proteins. Since animal mtDNA evolves faster than nuclear genetic markers, it represents a mainstay of phylogenetics and evolutionary biology. It also permits an examination of the relatedness of populations, and so has become important in anthropology and biogeography.

1. Mitochondrial DNA

   Mitochondrial DNA is the DNA located in organelles called mitochondria, structures within eukaryotic cells that convert the chemical energy from food into a form that cells can use, adenosine triphosphate. Most of the rest of the DNA present in eukaryotic cells can be found in the cell nucleus, and in plants, the chloroplast as well. In humans, mitochondrial DNA can be regarded as the smallest chromosome coding for only 37 genes and containing only about 16,600 base pairs. Human mitochondrial DNA was the first significant part of the human genome to be sequenced. In most species, including humans, mtDNA is inherited solely from the mother. The DNA sequence of mtDNA has been determined from a large number of organisms and individuals, and the comparison of those DNA sequences represents a mainstay of phylogenetics, in that it allows biologists to elucidate the evolutionary relationships among species. It also permits an examination of the relatedness of populations, and so has become important in anthropology and field biology.

Examples of mitochondrial dna in a Sentence

1. Benjamin Vernot:

   Mitochondrial DNA is only inherited from the mother, it's only one tiny thread of your ancestry and you lose a lot of complexity. If you look at the nuclear genomes of humans, Neanderthals or Denisovans, you can calculate how they were related and how many there were at a given time.

2. Doug Turnbull:

   The key message is that we have found no evidence the technique is unsafe. Embryos created by this technique have all the characteristics to lead to a pregnancy, this study using normal human eggs is a major advance in our work towards preventing transmission of mitochondrial DNA disease.
