At present, the international team of "Human Genome Project", composed of hundreds of scientists from Cambridge University, Keio University in Japan, Donghai University School of Medicine, Washington University and dozens of laboratories around the world, is trying to reveal and map 65.438+million genes and 3 billion base pairs of the human body. They will soon be able to find out the arrangement of all human genes, and then publish the complete information of all human DNA on the Internet to establish a complete gene information base. Once the human genome project is completed, it will become one of the most important achievements in the field of scientific research in history. It is a manual describing human beings themselves and a guide to the complete description of human body structure and operation. By then, more than 5,000 genetic diseases endangering human health, as well as cancers, cardiovascular diseases, arthritis, diabetes, hypertension, Alzheimer's disease, multiple sclerosis and mental diseases closely related to heredity, can be diagnosed and treated. This new breakthrough in the field of genetics will almost certainly lead to a medical revolution in 2 1 century. This discovery is more important than the first atomic bomb explosion and the human landing on the moon.
