Species Dna Barcoding Sections Explain Identification Involves Identifying

DNA barcoding involves identifying genome sections common to all species but varying between them for comparison, such as cytochrome c oxidase in animals. This method is quick and inexpensive for analyzing small DNA segments.

Le code-barres ADN consiste à identifier des sections du génome qui sont communes à toutes les espèces mais varient entre elles pour permettre des comparaisons, comme la cytochrome c oxydase chez les animaux. Cette méthode est rapide et peu coûteuse pour analyser de petits segments d'ADN.

Front Explain how DNA barcoding allows the identification of species.
Back DNA barcoding:
  • Barcoding involves identifying sections of the genome that are common to all species but vary between them to make comparisons
  • Example is cytochrome c oxidase that is similar in all species - enzyme for respiration but it varies enough to give clear differences between species (only works in animals)
  • It is quick and cheap just to analyse the small sections
