The Advantages Of DNA Barcoding

The material to be used for DNA barcoding is collected from plants, fungi, animals or products made from them. The advantage of DNA barcoding is that it can be used to identify DNA sequence even from small, damaged, or industrially processed material. First, a sample of tissue is collected, preserving the specimen whenever possible and noting its geographical location and local environment. A small leaf disc, a whole insect, or samples of muscle are suitable sources. A plant material is collected as a herbarium specimen and voucher specimen is deposited in the nearest herbarium. The herbarium specimen is labeled with a unique vouchering number. Plant voucher specimens vary in how and when they are dried after being pressed. If specimen-drying facilities are not immediately available, especially in humid tropical climates, botanists often treat pressed…show more content…
D. Hebert in 2003. However, research in DNA barcoding exceled and it has resulted in myriad of applications. It is a quick method as compared to classical taxonomic identification systems. In addition to assigning specimens to known species, DNA barcoding will accelerate the pace of species discovery by allowing taxonomists to rapidly sort specimens and by highlighting divergent taxa that may represent new species (Hebert and Gregory, 2005). DNA barcoding approach has become immensely popular and advances as well as limitations have clearly emerged as increasing amounts of organisms have been studied (Frezal et al., 2008). DNA barcoding is a rapid and efficient method for species level identification and it has revolutionized the taxonomic and biodiversity research (Hajibabaei et al., 2007). DNA barcoding has been proposed to play a key role in biodiversity assessment of both present day and past organisms’ communities (A. Valentini et al.,
