HOW A GENE IS SPLICED : Making a Genetically Modified Crop
To create a GM crop, plant geneticists isolate a gene (usually in another type of plant or a bacterium) that produces a desirable trait. They then introduce that gene into the DNA of the plant they wish to modify. These animations show how key parts of the process are accomplished. Click on an image to view the Flash animation.
