While important to different areas of biology, both are modeled on the concept of the Universal Product Codes (UPCs) used to identify products in supermarkets, with specific DNA sequences acting as the unique identifier. The importance of each is discussed here. DNA barcodes based on naturally-occurring sequences The original use for Kress and Erickson identified three criteria a gene region must satisfy “to be practical as a DNA barcode: ( i) contain significant species-level genetic variability and divergence, ( ii) possess conserved flanking sites for developing universal PCR primers for wide taxonomic application, and ( iii) have a short sequence length so as to facilitate current capabilities of DNA extraction and amplification (Kress).” The initial genomic region that fit these criteria was the mitochondrial cytochrome C oxidase 1 (COI) subunit gene. The COI gene region was discovered to be conserved across species of fish with enough species-specific sequence for identification purposes. The pertinent COI sequence i...

A "DNA barcode" is a unique DNA sequence that identifies each living thing. Short DNA barcodes, about 700 nucleotides in length, can be quickly processed from thousands of specimens and unambiguously analyzed by computer programs. With DNA barcodes, we can discover and catalog biodiversity on our planet using tools developed at the DNA Learning Center.

DNA Barcoding DNA barcoding of diatom symbionts of LBF specimens Amphistegina lobifera and A. lessonii indicated several endosymbionts, including the genus Ostreobium (Chlorophyta), a taxon that was particularly present in A. lessonii.

Narong Jaturas, in Encyclopedia of Bioinformatics and Computational Biology, 2019 Abstract DNA barcoding is increasingly used to obtain taxonomic information about unidentified organisms. DNA barcoding involves sequencing a short fragment of the mitochondrial cytochrome c oxidase subunit I (COI) gene, “DNA barcodes,” from taxonomically unknown specimens and performing comparisons with a library of DNA barcodes of known taxonomy. In this article, we provide beginners with step-by-step instructions for (1) converting raw DNA sequences into clean DNA barcodes (sequence editing, sequence alignment), and (2) commonly used tools for DNA barcode comparisons (to assign taxonomic names to DNA barcodes, and to cluster DNA barcodes into Operational Taxonomic Units). N. Anand, ... P.K. Dadheech, in Cyanobacteria, 2019 6.6Barcoding DNA barcoding involves the production of PCR amplicons from particular regions to sequence them and these sequence data are used to identify or “barcode” that organism to make a distinction from other species ( Lebonah et al., 2014). This method is widely used in euka...

DNA barcoding is used for more than just research – it can also help address problems with broad impacts on all areas in which society interacts with biodiversity. Some practical applications include pest and disease control, food production and safety, resource management, biodiversity conservation, and education.

DNA barcodes are short sequences from a standard region of the mitochondrial cytochrome c oxidase subunit 1 (CO1) gene. A simple method of obtaining a DNA barcode is described here. What does DNA barcoding involve? 1. Extracting DNA from the sample specimen In most cases, only a small amount of sample material (1–3 mm 3 – about the size of a match head) is required for DNA barcoding. The way the DNA is extracted depends on the source of the sample material and how old it is. Building DNA barcode reference libraries There are a number of DNA barcode reference libraries. For example, the International Barcode of Life Project (iBOL) completed the BARCODE 500K program. Research organisations from 25 countries barcoded 500,000 species. Building on this success, iBOL has launched BIOSCAN, which will extend barcode coverage to 2.5 million species by 2026!
