CHESTERFIELD, Mo. -- Behind a door marked "closed" to the thousands of visitors who tour the Monsanto Life Sciences Research Center here each year, Cindy Clasen fires a DNA-loaded .22-caliber shell into corn tissue, changing its genetic makeup.

The process, called genetic engineering, allows scientists to transfer a single gene from any organism -- plant, animal, or microbe -- into a food crop so it can withstand insects and herbicides, as well as last longer before spoiling.

"What we do is the same as Mother Nature," says Clasen, a Monsanto Co. research technician. Genetically engineered, or transgenic, crops look and taste the same as conventional crops, and are not ...
