Answer to Question #241964 in Cell Biology for geoge

Question

which of the following taxa have mitochondrial DNA?

Answer 1

Mitochondrial DNA (mtDNA or mDNA)^[3] is the DNA located in mitochondria, cellular organelles within eukaryotic cel ls that convert chemical energy from food into a form that cells can use, 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.

Mitochondrial DNA is the small circular chromosome found inside mitochondria. These organelles, found in all eukaryotic cells, are the powerhouse of the cell.^[1] The mitochondria, and thus mitochondrial DNA, are passed exclusively from mother to offspring through the egg cell.
