Confirmed the three-dimensional structure of DNA?

It was Wilkins who showed Watson and Crick the X-ray data that Franklin had obtained. The data confirmed the 3- D structure that Watson and Crick had theorized for DNA. In 1953, both Wilkins and Franklin published papers on their X-ray data in the same Nature issue as Watson and Crick's paper on the structure of DNA.

Why was DNA originally called Nuclein?

Miescher named his discovery "nuclein," because he had isolated it from the nuclei of cells. Today, his discovery is known as deoxyribonucleic acid (DNA).
