Description
Teach PCR, gel electrophoresis, and bioinformatics with this DNA barcoding lab activity, in which students determine the species of a mammal or insect based on the DNA sequence of its cytochrome c oxidase I (COI) gene, or a fungus based on the DNA sequence of its internal transcribed spacer (ITS). Students first extract DNA from tissue, use PCR to amplify the DNA, and perform agarose gel electrophoresis to verify PCR products. Next, after receiving DNA sequencing results from a third party (sequencing services not included), students then use bioinformatics to genetically identify the species using the sequence obtained. The unique COI or ITS sequence produced for a given sample is considered its DNA barcode.
With this kit, you can teach your students how to:
• Perform DNA extraction, PCR amplification, and gel electrophoresis up to 16 DNA and control samples (8 student workstations, 2 samples per workstation, 2–4 students per workstation)
• Use DNA sequencing and bioinformatics to determine species identity
• Perform investigations in their area to examine biodiversity or see if marketplace substitution is occurring
• Contribute to global initiatives for barcoding life (Barcode of Life Database)
