DNA barcoding is a taxonomic method that uses a short genetic marker in an organism's mitochondrial DNA to identify it as belonging to a particular species. It is based on a relatively simple concept: most eukaryote cells contain mitochondria and mitochondrial DNA (mtDNA) has a relatively fast mutation rate, which results in significant variance in mtDNA sequences between species and, in principle, a comparatively small variance within species.

  • DNA barcoding is a taxonomic method that uses a short genetic marker in an organism's mitochondrial DNA to identify it as belonging to a particular species. It is based on a relatively simple concept: most eukaryote cells contain mitochondria and mitochondrial DNA (mtDNA) has a relatively fast mutation rate, which results in significant variance in mtDNA sequences between species and, in principle, a comparatively small variance within species. However, because all mtDNA genes are maternally inherited (direct evidence for recombination in mtDNA is available in some bivalves such as Mytilus but it is suspected that it may be more widespread), any occurrences of hybridization, male-killing microoroganisms, cytoplasmic incompatibility-inducing symbionts, horizontal gene transfer (such as via cellular symbionts), or other "reticulate" evolutionary phenomena in a lineage can lead to misleading results (i.e. , it is possible for two different species to share mtDNA, or for one species to have more than one mtDNA sequence exhibited among different individuals). A 648-bp region of the mitochondrial cytochrome c oxidase subunit I (COI) gene was initially proposed as a potential 'barcode'.
  • DNA Barcoding (zu deutsch DNA-Etikettierung) ist eine taxonomische Methode zur Artenbestimmung anhand eines Markergens aus der mitochondrialen DNA (mtDNA). DNA Barcoding basiert auf einem relativ einfachen Konzept: die meisten eukaryotischen Zellen enthalten Mitochondrien. Mitochondriale DNA (mtDNA) hat eine hohe Mutationsrate. Daher unterscheidet sich die mtDNA unterschiedlicher Arten wesentlich mehr als die mtDNA zweier Individuen derselben Art. Als genetischer Marker wird eine 648 bp Region des Gens der Untereinheit I der Cytochrom c Oxidase (COI) verwendet. Allerdings kann es aufgrund von Horizontalem Gentransfer zu fehlerhaften Ergebnissen kommen.).
  • Il DNA barcoding è una metodica molecolare sviluppata per l'identificazione di identità biologiche, che si basa sull'analisi della variabilità di un marcatore molecolare. Nel mondo animale, i cosiddetti metazoi, il marcatore principalmente utilizzato è un frammento del gene mitocondriale, codificante la subunità I della citocromo ossidasi, coxI.
  • DNA-barcoding is een taxonomische methode die aan de hand van korte genetische merkers uit het mitochondriaal DNA soorten benoemt. Vele eukaryote organismen bevatten mitochondria, dus is er maar één universele methode nodig om soorten te determineren. Bovendien vertoont het mtDNA een snelle mutatiesnelheid, zodat er voldoende verschillen en dus onderscheidingscriteria tussen soorten te vinden zijn. Voor DNA-barcoding bij dieren wordt algemeen het CO1-gen of "cytochroom c oxidase subunit1"-gen gebruikt.
