After the war, Franklin sought a more stimulating scientific environment. In 1947, she moved to Paris to work at te Laboratoire Central des Services Chimiques de l 'État, when e joind the group of Jacques Méring.

Randall wrote a letter to Wilkins stating that Franklin would be his assistant, but he never communicate this to Franklin herself.

Later Career at Birkbeck College: Contributions to Virology

After leaving King 's Collegie in 1953, Franklin moved to Birkbeck College, were established her own X- ray crystallogography laboratory.

Konkluzja

Rosalind Franklin 's contributions to discale thee discarey of DNA' s double helix were not merely supportiva; they y were foredationol. Her X- ray diffraction images, especialle photograph 51, and her analytications provided thee empirical basions for thee model that transformed biologics. Without her data, Watson and Crick would have lacked thee critel revence to build their double helix. Beyond DNA, her piering work the structure of virtuse of paved thee for nexular virology.
