Genspace welcomes new barcoders as well as those who want to finish what they started in the last session. There are plenty of plant samples to go around :-)
For a description of the project, check out
DNA barcoding consists of extracting the DNA from the plants, PCRing it with primers that amplify the barcode region, checking it with gel electrophoresis, and sending it out for DNA sequencing. Establishing DNA barcodes for all species on earth is a large collective scientific effort. The plants of the Alaskan tundra are particularly fragile and affected by global warming. Establishing their identities via DNA barcoding will make it easier for students and citizen sceintists to contribute to ecological surveys. So you will be contributing your time to a worthy effort, and might even get your name in the official Barcode of Life database if the plant you are working on has never been barcoded before.
