GMOs Web Tour
This web tour begins by reviewing the history of plant breeding. That is followed by a look at the science that allows us to genetically engineer crops. We end our web tour with a look at evaluation and regulation of genetically engineering crops.

1Plant Breeding Activity
This interactive activity goes through the basic process used in a traditional breeding program. Crossing, genetic variation, selection and elements of DNA technology are discussed within this activity. The material is aimed towards high school or introductory life science undergraduate students.

6Making a Recombinant Plasmid
This animation shows how a plasmid responsible for encoding a gene can be cut. The plasmid can be altered with the addition of linear DNA to form a recombinant plasmid to encode a new gene of interest. This is the first of four animations detailing the gene cloning process.
