This film tells the story of the scientists and the evidence involved in one of the most important scientific quests of the 20th century: the discovery of the structure of DNA. James Watson and Francis Crick collected and interpreted key evidence to determine that DNA molecules take the shape of a twisted ladder, a double helix. The film presents the challenges, false starts, and eventual success of their chase, culminating in the classic publication in Nature on the structure of DNA. An audio descriptive version of the film is available via our media player. Franklin, Rosalind E. Watson, J. Wilkins, M. Stokes, and H.

Protection from damage — A-DNA is far less susceptible to ultraviolet ray damage, and spore-forming bacteria have been shown to adopt an A-DNA conformation, which may be a protective change. These are nitrogenous bases attached to phosphate groups and ribose sugars. In the long-term, DNA is a storage device, a biological flash drive that allows the blueprint of life to be passed between generations2. Related Topic Pages. Social studies.
