Abstract:
Scientists have estimations indicating that of the 8-10 million species that live on our earth, only two million of them have been identified and studied. Traditional identification techniques are time consuming and need specially trained individuals to perform them and is not always error proof. With the advent of DNA Barcoding, scientists revealed that one species of butterfly is actually ten species, with caterpillars that eat ten different plants. In contrast to the traditional techniques, DNA Barcoding is more accurate, and efficient. Just as the barcode is a combination of unique bars which form a universal identifier for that particular product, DNA barcode is a DNA sequence that is unique to each species of living organisms can be used to identify and compare them with the existing large sequences in the databases. DNA barcode consists of a standardized short sequence of DNA between 400 and 800 base pairs long which is extracted from mitochondria in animals and chloroplats in plants that in theory can be easily isolated and characterized for all species on the planet. By harnessing advances in molecular genetics, sequencing technology, and bioinformatics, DNA barcoding is allowing users to quickly and accurately recognize known species and retrieve information about them. It also has the potential to speed the discovery of the thousands of species yet to be named. This seminar mainly deals with forensic applications of DNA Barcoding in the field of wildlife conservation, authentication of food products, validation of raw drugs.
