WebWith the general acceptance of DNA as the chemical basis of heredity in the early 1950s, many scientists turned their attention to determining how the nitrogenous bases fit together to make up a threadlike molecule. The structure of DNA was determined by American geneticist James Watson and British biophysicist Francis Crick in 1953.
