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 ...

DNA’s structure doesn’t have to be just a double helix: by fiddling with the order of bases or substituting other molecules, the strand can be cause to make a hard right turn, or curve around ...

They’re models. We know that DNA exists in this double helix because it’s the only shape that can explain the X-ray diffraction patterns it forms.

The double helix model of DNA may not be at the center of everything after all, with British scientists discovering a natural four-standed helix.

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 ...

It’s the most famous corkscrew in history. Now an electron microscope has captured the famous Watson-Crick double helix in all its glory, by imaging threads of DNA resting on a silicon bed of ...
