First observed by Richard Altman (1894) Term mitochondria was coined by Carl Benda (1898) They produce enzymes for the metabolic conversion of Richard Altman Carl Benda 3 The structure of the DNA is double-stranded, circular, and about 16,569 bp in length for human mitochondria. One non coding part of the DNA, called the D-loop, is triple stranded and contains extra 7S DNA. Generally, there are 2 to 10 copies of the DNA in each mitochondrion and many mitochondia in each cell Mitochondrion, membrane-bound organelle found in the cytoplasm of almost all eukaryotic cells (cells with clearly defined nuclei), the primary function of which is to generate large quantities of energy in the form of adenosine triphosphate (ATP).
