Key concepts Biology Life DNA Double helix Introduction Ever wondered how DNA, the genetic blueprint of a life-form, can encode and pass on the information on how to grow and maintain that life ...

This led to a Hoogsteen model of the DNA double helix 14 that did not fit the diffraction data as well as the Watson-Crick model, but one could rely on the fiber diffraction data only to a limited ...

The results reveal the corkscrew thread of the DNA double helix, clearly visible. With this technique, researchers should be able to see how single molecules of DNA interact with other biomolecules.

Researchers have imaged in unprecedented detail the three-dimensional structure of supercoiled DNA, revealing that its shape is much more dynamic than the well-known double helix.
