Description
Advanced – For experienced high school and college classes; requires some basic technical skill.
Explore a modern application of genetic engineering through this exciting laboratory activity. Many commercial crops are genetically modified (GM) to include a transferred gene (transgene) for herbicide resistance. This activity investigates whether the soy or corn ingredients in various processed foods contain a genetic modification. Students isolate DNA from wild-type and GM plant material (provided controls), and from food products of their choice. They use the extracted DNA as a template in 2 separate PCR reactions run under the same conditions. One reaction serves as a positive control to amplify a portion of the tubulin gene found in all plants, and the other assays for genetic modification. Each group works with a plant control and a food product.
Kit includes materials for 25 PCR reactions and a voucher to request perishable materials later at your convenience. Contact us or return voucher to request delivery of perishables.
Note: Order kit to arrive 1 month before performing lab.
