Rosalind Franklin, a scientist at the University of London, had already documented the helical nature of DNA when Watson and Crick accessed her unpublished data without permission and used it to ...

A centrifuge was used to separate DNA molecules labeled with isotopes of different densities. This experiment revealed a pattern that supports the semiconservative model of DNA replication.

At King's College in London, Rosalind Franklin and Maurice Wilkins were studying DNA. Wilkins and Franklin used X-ray diffraction as their main tool -- beaming X-rays through the molecule yielded ...

The leader of the team assigned her to work on DNA with a graduate student. Franklin's assumption was that it was her own project. The laboratory's second-in-command, Maurice Wilkins, was on ...

A previously overlooked letter and a news article that was never published, both written in 1953, add to other lines of evidence showing Rosalind Franklin was an equal contributor — not a victim — in ...
