to argue that DNA actually takes the form of a double helix, a ladder-like structure that is twisted along its entire length (Figure 6). Franklin, Watson, and Crick all published articles ...

In 1953, Francis Crick and James Watson described the molecular shape of DNA as a "double helix." Double-stranded DNA is composed of two linear strands that run opposite to each other, known as ...

Chances are you've seen an illustration of DNA's double-helix structure and even pictures of the chromosomes that comprise the human genome. But where and how does the famous double helix fit into ...

Not all DNA is in the double helix form described in textbooks since the 1950’s. Quadruple helix DNA, also known as G-quadruplex DNA, was identified in the human genome several decades ago, and ...

Franklin, working mostly alone, found that her x-ray diffractions showed that the "wet" form of DNA (in the higher humidity) had all the characteristics of a helix. She suspected that all DNA was ...

This showed that DNA had a helix shape. Without her knowledge, one of her colleagues showed the picture to James Watson. When he saw it, he knew that his and Francis Crick’s theory about the ...
