       On June 26, 2000, two scientists, called Francis Collins and Craig Venter, told the world that they

could now read the whole "map" of the human body: DNA. DNA is something that everybody has, and

it tells the body what to do. DNA is the reason that we look like our mother and father, because we get

some of their DNA to make our own.    

       People have been trying to understand the human body for a long time. In 1860, Gregor Mendel

discovered a special reason why we look the same as other people in our family. It is because of small

things named "genes" in our body. In 1953, James Watson and Francis Crick made another discovery

and found out that those small parts are real messages written in the DNA with a special language.

       In 1961, Marshall Nirenberg and Johann Matthaei found a message in DNA showing how DNA

tells the cell (细胞) to build its parts. Scientists have now found all the words in the DNA map, but we

still do not understand what they all do. By understanding what just one "word" means, we can help

save more people from several illnesses.

       Most people hope that this will help make better medicine and help sick people. Other people worry

that when people begin to know more words and find out lots of other information, we might use it in a

wrong way, just to make people more attractive, or stop sick people from getting jobs. Man would have

to meet a lot of trouble if DNA technic wasn’t limited in use.
