Barcoding life
DNA barcoding is a taxonomic method that uses a short genetic marker in an organism's mitochondrial DNA (mtDNA) to identify it. Cells of the higher organisms contain mtDNA, which are prone to mutation. It happens because mtDNA do not rearrange themselves. This gives rise to variations that can be easily measured. It was believed that a particular region of the mitochondrial gene, known as COI, represents a potential
