DNA Barcoding Invertebrate Lab Report #1 Example | Topics and Well Written Essays - 500 words

desoxyribonucleic acid Barcoding Invertebrate 1 - Lab Report ExampleCurrently two such databases exists, the Barcode of life ( fearless) and The planetary Nucleotide Sequence Database Collaborative which is an intiative of the three main Nucleotide databases, GenBank, EMBL and DDBJ. The f out(p)h and final stage is to carry out an analysis where specimens are identified with the closest matching reference record in the aforementioned databases.In this lab report, we sought to perform a barcode analysis using mayfly desoxyribonucleic acid sequences in the BOLD database. The barcode sequence is mainly a short DNA sequence which has a uniform location in the genome and is used to identify species. One of the commonly used sequence in DNA barcoding is the cytochrome oxidase subunit 1 (COI). This was the sequence we used this work. The barcoding process involves identifying a universal locus which has retained enough sequence saving throughout evolution and can be sourced from many orga nisms. This sequence should also be diverse so as to be competent enough to differentiate a gull species to the family level. Generally regions of the chloroplast (rbcL gene) and the mitochondria (COI) meet these requirements. variant studies have been undertaken by Herbert et al (2003a, 2004b) and established this COI sequence as the sequence of choice in DNA barcoding in insects and vertebrates. Inverterbrates such as mayfly are collected whole and may be euthanized in a kill jar by placing them in a freezer. In the lab, primers are designed to target the conserved regions flanking the rbcL or the COI
