Short Introduction of Dna Barcoding

Abstract

DNA barcoding is a system for fast and accurate species identification. It’s creates ecological system more accessible by using short DNA sequence instead of whole genome and is used for eukaryotes and prokaryotes. The short DNA sequence is generated from standard region of genome known as marker. This marker is different for various species like CO1 cytochrome c oxidase 1 for animals, matK and rbcL for plants and Internal Transcribed Spacer (ITS) for fungus. It has many uses in various fields such as agriculture, sustaining natural resources, protecting endangered species, water quality, preserving natural resources, identification of medicinal plants.
