    DNA barcoding uses a short section of DNA from an organism to create a unique barcode. The DNA barcodes, or sequences, are stored in databanks and used to identify organisms.

    This scheme is similar to the barcodes placed on items we purchase from the supermarket.

    Note: this is a simulated example of a DNA barcode.
