Abstract: The author elucidated the milestone significance of the double helix model of DNA structure in three aspects at the 50th anniversary of the model proposed: its influence on the allocation of research resources, on the regime change of the life science researches, and its impact on the entire scientific community and society. It has been concluded that the progress of science and technology is irresistible, and the rationality of the human being will finally shine in the dark and bring our society a promising future.

Key words: double helix model of DNA structure, allocation of research resources, research regime change, rationality of the human being
