But those communities and policy makers are also careful about the scientific door they are opening as the project uncovers the secret of life.For the last few years, the genetic advances in the fastdeveloping field of biotechnology(生物技术) have provided material for all kinds of work, but the developments of modern science in unlocking the secrets of the human genetic code have opened a world of possibilities for human health, as well as for the popular imagination.While European and Japanese researchers are making rapid progress in decoding(解码) human DNA, the leading organization for genetic research in the United States, which began in 1990, is “unlocking the code” of the human body to learn how to defeat fatal diseases. Already, the Human Genome Project has become widely known and praised for finding the genes connected with as yet terrible diseases, and making progress toward separating the genes that show a sign of breast cancer or AIDS.Once these genes are found and studied, researchers can develop new ways to attack infections, and genetic diseases. Medical companies are very interested in mapping the human genome, as they expect to develop a lot of new drugs for these illnesses.1.
