Explore a modern application of genetic engineering through this exciting laboratory activity, which investigates whether the soy or corn ingredients in various processed foods contain a genetic modification. Students isolate DNA from wild-type and genetically modified (GM) plant material (provided controls), and from food products of their choice. Kit includes materials for 25 PCR reactions.
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 prepaid coupon to request perishable materials later at your convenience. Contact us or return coupon to request delivery of perishables. Note: Order kit to arrive 1 month before performing lab.

Carolina Biological and the Cold Spring Harbor Laboratory's DNA Learning Center (DNALC) have partnered together since 1986 to make molecular genetics and biotechnology more accessible to students globally. Focused on creating innovative classroom activities that give students the opportunity to go hands-on with DNA and explore the core principles of genetics. Together we have constantly worked to increase the accessibility of many key scientific breakthroughs for classrooms globally, including such techniques as PCR, DNA Sequencing, and RNAi.
Bringing a Carolina and DNALC kit into your classroom introduces your students to the experience of scientific research on its highest level, in some cases Nobel Prize winning research, with ease and simplicity. Each kit features in-depth background information, classroom tested protocols, pre-packaged materials, and the knowledgeable technical support of the Carolina Biological team. Our wide selection of kits in this series offers educators' unmatched opportunities to bring biotechnology or genetics into their classroom, with a best in class product.
At Carolina, we believe that innovative research doesn't just belong in a lab—it belongs in your classroom.
The DNA Learning Center (DNALC) is the world's first science center devoted entirely to genetics education and is an operating unit of Cold Spring Harbor Laboratory, an important center for molecular genetics research. The mission of the DNA Learning Center is to prepare students and families to thrive in the gene age. We envision a day when all elementary students are exposed to principles of genetics and disease risk; when all high school students have the opportunity to do hands-on experiments with DNA; and when all families have access to genetic information they need to make informed health care choices.
