... the positions of atoms in the molecule. Once DNA had been identified, as the genetic material scientists were keen to use the same technique to study at DNA. This was not easy because DNA was difficult to crystallise. Two of the scientists who succeeded in overcoming the technical difficulties were Rosalind ... is present. Both scientists showed that DNA was a helix. It is the B form of DNA that proved to be more biologically important. Meanwhile James Watson and Francis Crick were working with atomic models at Cambridge. Not much was achieved until Watson went to Kings College to have...
