Paul Hebert Dna Barcoding

Satisfactory Essays
DNA barcoding is an important way to identify organisms. It was first brought up in 2003 by Paul Hebert. He proposed using a short line of DNA from a specific part of the genome to discover and identify new species and differentiate previously known species. This method reads the DNA sequence like a barcode on an item at the grocery store to identify different ones. In most animals, there is a 648 base-pair region in the mitochondrial DNA that is used in DNA barcoding because it is quick and accurate to sequence but contains enough variation to distinguish different species.
Since this barcoding method uses DNA to differentiate organisms, it is much more accurate than just identifying the organisms by what they look like. Through this more
