Rosalind Franklin's reasoning on the DNA structure, Raymond Gosling

Interviewee: Raymond Gosling. Raymond Gosling - Rosalind Franklin's graduate student - talks about Franklin's view on model building. (DNAi Location: Code > Finding the structure > Players > Rosalind Franklin > Building models)

But her view was you could build models all day and you could probably generate as many models as you had time for hot dinners. But how did you prove which one was right? On the other hand we had a diffraction photograph with best part of a hundred separate reflections. If you made the measurements, you measured their intensities and their positions, you did all the corrective geometry, and you put them into the equations, you would let the data speak for itself, and out of that would come a definitive structure. And it was only when you got to that stage, should you think of model-building. She didn't rule it out but she just thought it was a waste of time until you'd done, until you'd let the x-ray diffraction speak for itself.
