Letter from Rosalind Franklin to James D. Watson
Description:
In this letter, Franklin noted her recent crystallography results, and what they might indicate about the structure of TMV. She later found that Watson's guess regarding the location of the RNA was correct.

Dear Jim,
Many thanks for your letter, which I ought to have answered sooner. I have now had from Casper a lot more details about his work, and I look forward to discussing it and other TMV problems with you soon.
I recently collected some repolymerised A-proteins from Schramm. From this I have now obtained an X-ray diagram which is almost indistinguishable from a good TMV diagram except on the meridian and equator. That is, the non-meridional, non-equatorial part of the TMV diagram must be due almost exclusively to protein. I mention this because of your remark that the RNA must fit the TMV helical grid. This may well be true, on the other hand I think, as far as the X-ray data are concerned, a disordered RNA core would fit in the picture equally well.
I shall probably be sending you a short paper in a few days.
Best wishes,
Yours
