Bacorde DNA


The classification by "barcode" DNA is a scientific movement that has the purpose to catalog all life on Earth with a simple standardized genetic tag, in a similar way in concept to how the products in stores are labeled with unique barcodes. But this approach, as is currently implemented, leads to some results as uncertain as that of a bar code reader to read the label supermarket a block and accounted for as an orange, a new study Brigham Young University. Following the results of the work, the authors recommend specific procedures for quality control to ensure that the right genes are recorded. It is important to thoroughly check all scientific tool because all have limitations, and some situations are more favorable to apply the "barcode" than others. Organisms can be identified no matter what stage of life they are. For example, the larvae of mosquitoes that carry malaria contain the same DNA as the adult version of the insect to which it is intended erradicar.


But the new study has shown that current techniques can mistakenly record copy "broken" gene present in the nucleus cells of the body. This non-functional copy can be similar enough to that bar code technology to record it, but instead lead to errors. Advocates of "barcode" DNA looking to establish a short genetic sequence as a way to identify species, in addition to traditional methods based on external physical characteristics.

Hi,
What is the purpose of using this system? Is it only to know the different species?
Thanks
