DNA Barcodes: A New Tool for Biological Identifications?

Abstract

DNA barcode is a new concept that applies gene or universal DNA sequences differences to support classification of organisms. At present, there has been collaboration between various institutions around the world to create a database of DNA barcode of life. DNA barcode can be applied to the biological diversity in a variety of different dimensions. However, the application of DNA barcodes still has several limitations, for example universal DNA sequences or standardized nucleotide sequences, acquisition of a life and limited of database. In conclusion, DNA barcode is just a tool that assists to support the existence of life which necessary come together with other methods to identify biological specimens are more reliable.
