What is DNA barcoding?

Posted June 4, 2024


Answer

DNA barcoding is a method of identifying species by comparing short, standardized DNA sections from a specific gene or genes. It is based on the principle that every species has its own barcode, just as every individual has their own fingerprint. Individual sequences can be used to uniquely identify an organism to the species level by comparing DNA barcodes with a reference library of DNA sections or sequences.
