If it weren't for her analysis of x-ray diffraction of DNA,
Watson and Crick might not have been first with correct double-helix
model.

Any other important birthdays coming up before August 1?

Did she anayze it, or was it a case of being talented at getting
diffraction pictures?

As I recall from some reading, it was her photos and the measurement of a
crucial length in the structure that was passed to Crick and Watson without
her knowledge. This information led them to realise that they were
constructing their model incorrectly, and the revised structure gave them
the double helix model.

Rosalind Franklin had come up with the idea of a helical DNA structure in
her notes but hadn't published it yet as she was doing more experiments.
Her approach was observational, while their approach was to take the basic
amino acids and model what structures might emerge from their bonding
properties.

Amino acids???

And yes, she was the very best of x-ray crystallographers of her generation.
No one else was getting results of that quality. If she had lived long
enough I think she would have shared the Nobel.

I heard that she died of cancer, perhaps resulting from x-ray
radiations.
Crick had long life and Watson is still alive instead...
