Core Viewpoint - James Watson, the co-discoverer of the DNA double helix structure and Nobel Prize laureate, passed away at the age of 97, marking the end of an era in molecular biology and genetics [2][3]. Group 1: Contributions to Science - Watson and Francis Crick proposed the DNA double helix model in 1953, which unveiled the secrets of life's genetic code and laid the foundation for modern molecular biology and biotechnology [2][3]. - The DNA double helix is regarded as one of the "three great scientific wonders of the 20th century," alongside Einstein's theory of relativity and Heisenberg's quantum mechanics, signifying a shift in biology from descriptive to molecular science [4]. Group 2: Academic and Professional Achievements - Watson served as a researcher at Harvard University from 1955 to 1956 and was a biology professor from 1956 to 1976, during which he authored "Molecular Biology of the Gene," a textbook that became a cornerstone for generations of biologists, selling over one million copies globally [5]. - As the director of Cold Spring Harbor Laboratory from 1968, Watson transformed the institution into a leading center for molecular biology research and established the "James Watson Scholarship" [5]. Group 3: Legacy and Influence - Watson had a significant impact on the Chinese scientific community, fostering collaborations since the 1980s and promoting academic exchanges in molecular biology [5]. - He expressed pride in witnessing China's emergence as a leader in genomics and aimed to establish a world-class life sciences center in Shenzhen, named after him, to focus on cancer and genetics research [5].
