But the most important use of the new understanding of our genetic sequence will be in medicine and will change it __1__. By looking at our genetic make-up and how it __2__ between individuals we can learn why some people __3__ better to drug treatment than others. Doctors hope that by isolating the genes that respond to __4__ drugs we can pinpoint exactly what we need to do to __5__ a problem. The final hope, of course, is to identify possible problems such as cancer before they __6__. Then we may be able to __7__ special drugs that are __8__ for particular groups of __9__. The possibility of being able to intervene and stop problems before they happen has led to accusations that we are "__10__ with nature". Like other great scientific advances, the sequence of the human genome can be used for good or bad purposes.
