DNA barcoding is a method of species identification using a short section of DNA from a specific gene or genes. The premise of DNA barcoding is that by comparison with a reference library of such DNA sections (also called "sequences"), an individual sequence can be used to uniquely identify an organism to species, just as a supermarket scanner uses the familiar black stripes of the UPC barcode ...

Because of its web-based delivery and flexible data security model, it is also well positioned to support projects that involve broad research alliances. [3] Data release of BOLD mainly originated from a project BARCODE 500K [5] executed by the International Barcode of Life (iBOL) Consortium from 2010 to 2015. It aimed for data acquisition of ...
The DNA barcoding of animals (and specifically of bats) is used as an example in the diagram at the right and in the discussion immediately below. First, suitable DNA barcoding regions are chosen to answer some specific research question. The most commonly used DNA barcode region for animals is a segment about 600 base pairs long of the ...
DNA barcoding in diet assessment is the use of DNA barcoding to analyse the diet of organisms. [1] [2] and further detect and describe their trophic interactions.[3] [4] This approach is based on the identification of consumed species by characterization of DNA present in dietary samples, [5] e.g. individual food remains, regurgitates, gut and fecal samples, homogenized body of the host ...

The key concept for barcoding macroinvertebrates, is proper selection of DNA markers (DNA barcode region) to amplify appropriate gene regions, using PCR techniques. The DNA barcode region needs to be ideally conserved within a species, but variable among different (even closely related) species and therefore, its sequence should serve as a ...
The barcoded DNA fragments are amplified using PCR to create a library of DNA fragments with identical barcodes. All the fragments derived from a given DNA molecule are tagged with the same barcode. [4] This step increases the quantity of DNA for sequencing and reduces the chances of losing unique DNA fragments during sequencing.
