1953 In February, two unknown young people, relying on their beautiful scientific intuition, discovered the double helix structure of DNA in Cavendish laboratory of Cambridge University. On April 25th, 1953, Nature, an authoritative scientific magazine, published their carefully worded short article, and announced this discovery to the whole world, which attracted the attention of the whole world and set off a scientific storm to explore the gene "gold mine". This laid the foundation of modern molecular biology and was recognized as the greatest scientific discovery in the field of life sciences in the 20th century. One of the two young men is James? Davy. Watson.

Watson was born in Chicago on April 6, 1928, and spent his boyhood in Chicago, USA. At that time, his father liked bird watching very much. At the age of seven, Watson got his first book about birds from his father, which introduced the knowledge about bird migration. After reading this book, Watson had some questions. For example, how do birds fly long distances from the northern hemisphere to the southern hemisphere? Can young birds be found? Watson was attracted by these questions. However, it was almost impossible to get the answers to these questions at that time, because it was considered a miracle. When he grows up a little, Watson will go bird watching with his father every Sunday. Later, Watson learned about Darwin's theory of evolution, so he became interested in the question "What is the root of life" and always wanted to know why "life" can exist.

Subsequently, Watson went to public high school for two years. In the ninth grade, he took the course of "General Science". 10 grade, student biology. Through these courses, Watson learned about the knowledge and genetic laws of genes, and also learned that genes located on chromosomes can give instructions to determine the color of eyes and hair, but how to do it is not clear.

/kloc-When he was 0/5 years old, Watson went to the University of Chicago to study. In college, Watson took a general biology course. He studied genetics at first, but he found it boring. He still finds it interesting to study birds and their behavior. In the third year of college, Watson accepted some slightly in-depth courses, all related to ecology. Watson is interested in biological behavior patterns and ecology. In the process of studying ecology, after reading the book What is Life by Austrian physicist Schrodinger, he listened to the lecture by the famous geneticist Wright with great interest. Wright was an excellent geneticist when he was teaching at the University of Chicago. He is deeply interested in how genes work. His attention also shifted from birds to genes. At the age of 22, Watson received a doctorate in zoology.

In Watson's college days, biology was not regarded as a high-level science, and the real frontier science was physics, so very excellent talents did physical research. But Watson is very interested in biological research. After graduating from the University of Chicago, he wants to go to California Institute of Technology for further study and research. 1946 In the autumn, Watson sent out his application, but he was not accepted by California Institute of Technology. The reason is that they think Watson is just a student who has received simple biology training and has never studied most physical chemistry classes. However, Watson did not give up. He continued to apply to Indiana University, and this time he was accepted. Indiana University has the second highest level of research in genetics and is an excellent university. Like Caltech, it is at the forefront of genetic research.
