| Summary: | In 1953 James Watson and Francis Crick interpreted a now iconic image taken by Rosalind Franklin and Raymond Gosling. Franklin and Gosling had used X-rays to photograph a crystallized sample of deoxyribonucleic acid (DNA). By analyzing the fuzzy two-dimensional crossed-ladder image of the molecule (figure 2.2), Watson and Crick were able to interpret the elegant double-helical structure of DNA and ultimately to infer its function from this structure.* This achievement and other monumental discoveries in molecular biochemistry—such as Kendrew’s mapping of myoglobin (1958), Perutz’s mapping of hemoglobin (1959), and Hodgkin’s mapping of insulin (1969)—are part of a tradition |
