DNAbarcodingul
DNA barcoding is a taxonomic technique that uses a short genetic marker in an organism's DNA to identify it as belonging to a particular species. The standard DNA barcode for animals is a specific region of the mitochondrial cytochrome c oxidase subunit I (COI) gene. For plants, the chloroplast genes rbcL and matK are commonly used, although a combination of other markers is often necessary due to lower variation in these regions. This method relies on the principle that a standardized gene region, present in most multicellular organisms, will evolve at a rate that allows for species discrimination while remaining conserved enough for amplification across diverse taxa.
The process involves extracting DNA from a sample, amplifying the target barcode region using polymerase chain
