Watson and crick model of dna: In 1953

In 1953, James Watson and Francis Crick made a groundbreaking contribution to the understanding of DNA structure. By combining physical and chemical data, they proposed a model for DNA as a double helix, a twisted molecule consisting of two complementary strands held together by hydrogen bonds. This model revolutionized our knowledge of genetics and unlocked the genetic code that underlies all living organisms. Learn how Watson and Crick built on the work of previous scientists to propose the double helix model of DNA in 1953. Explore the history of DNA research from Miescher to Levene to Chargaff and beyond. The discovery in 1953 of the double helix, the twisted-ladder structure of deoxyribonucleic acid ( DNA ), by James Watson and Francis Crick marked a milestone in the history of science and gave rise to modern molecular biology, which is largely concerned with understanding how genes control the chemical processes within cells. In short order, their discovery yielded ground-breaking insights into the genetic code and protein synthesis. During the 1970s and 1980s, it helped to produce new and ...
