genetic modification

Scientists figured out a way to take genes from one species and stick them inside the DNA of another species. When a plant's DNA is changed, it develops different traits. This technology can create insect-resistant corn and tomatoes that stay fresh for longer periods of time. But critics call these new products "Frankenfood" and say that gene-switching is harmful.

Where developed: the U.S.
When developed: the 1970s
It means: traits are transferred from one organism
to another
Examples of modified organisms: corn, giant salmon, strawberries, tomatoes, rice, bananas
Why it's important: to improve the quality and quantity of food and to make food that has "built-in" medicine
