Despite her contribution to the discovery of DNA's helical structure, Rosalind Franklin was not named a prize winner: She had died of cancer four years earlier, at the age of 37.

When this DNA is collected and purified, the result is a whitish, sticky substance that is somewhat translucent. To actually visualize the double-helical structure of DNA, researchers require ...

double-helical model for the structure of DNA. Watson and Crick's discovery was also made possible by recent advances in model building, or the assembly of possible three-dimensional structures ...

The largest of these loops results from the helical coiling of chromatin ... piece together the first accurate model of DNA. Shown here is the structure of naked DNA -- DNA without all of the ...

Switchback DNA has only two strands, so it can be directly compared with the double helical structure of DNA that everyone is ...
