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 double helix, though, is not the only form in which DNA exists. For the first time ever, scientists have identified the existence of a new DNA structure that looks more like a twisted ...

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.

On February 28, 1953, James Watson and Francis Crick informally announced that they had discovered the double-helical structure of DNA. They soon reported their find more formally. On April 25 ...

In the middle of the 20th century, accumulating data suggested that DNA carries life ... to cytosine between the two helical backbones, adding that the proposed structure “immediately suggests ...

B-DNA is the most common form of DNA and has a right-handed double helix structure. A-DNA forms in a shorter, right-handed double helix. The function of this form is to protect DNA. DNA will ...

The discovery of DNA's double helix structure 70 years ago opened up a world of new science — and also sparked disputes over who contributed what and who deserves credit. Much of the controversy ...

So, Watson traveled to London to urge Franklin to begin building a model to work out DNA’s structure before Pauling did. As soon as Watson saw the photograph, he recalled in “The Double Helix ...

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

More than seven decades later, mathematician Robert Monjo believes he has discovered a similarly significant double helix — but this time not as the structure of human DNA, but as the structure ...
