Explore a modern application of genetic engineering through this exciting laboratory activity. 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. Each group works with a plant control and a food product.

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. Each kit includes materials for 25 PCR reactions. Note: Order the kit with the perishable materials included (kit and perishable components ship separately and may arrive on different days) or with a voucher to request perishables later at your convenience. Contact us or return the voucher to request delivery of perishable materials. Order kit to arrive 1 month before performing lab.
