How an X-ray diffraction pattern is created and how the DNA X-ray diffraction pattern can be interpreted to give the dimensions.
How to obtained an X-ray diffraction pattern. Wilkins had a different DNA pattern from Rosalind Franklin. Wilkins provided Franklin with the DNA.
Maurice Wilkins obtained some of the first X-ray diffraction patterns of DNA from which dimensions could be calculated.
Rosalind Franklin in the 1950s.
Raymond Gosling - Rosalind Franklin's graduate student - talks about Franklin's view on model building.
James Watson and Francis Crick solved the structure of DNA. Other scientists, like Rosalind Franklin and Maurice Wilkins, also contributed to this discovery.
James Watson and Francis Crick explain how they solved the structure of DNA. Erwin Chargaff explain how he measured the levels of each of the four nitrogenous bases.
James Watson talks about his partnership with Francis Crick.
