WebDec 27, 2024 · In the 1950s, James Watson and Francis Crick made a major discovery about DNA when they figured out its structure. They showed that DNA is a double helix, made up of two strands. This discovery was very important because it helped scientists understand how genetic information is stored and passed on. WebUsing both information about DNA’s composition and results from experiments aimed at uncovering DNA’s structure, Watson and Crick developed a physical model of DNA. In “A Structure of Deoxyribose Nucleic Acid,” Watson and Crick described DNA as a double helix that contained two long, helical strands wound together. forever lebanon valley contest
