Question: In the past 25 years, we have learned a lot about DNA, and are now able to manipulate genes. Plants are genetically modified to possess desirable traits such as resistance to disease and to grow with less water and fertilizer. There are even certain Idaho potatoes that all grow to the same size, so McDonald's french fries are the same length! Human genes are inserted into bacteria to inexpensively produce drugs that treat diseases. Soon, non-life threatening cosmetic changes will be available for those who can afford them.
