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 ...

Scientists still needed to figure out this molecule's structure to be sure, and to understand how it worked. In 1948, Linus Pauling discovered that many proteins take the shape of an alpha helix ...

However, the structure of the winged-helix protein, hRFX1, bound to DNA reported in a recent issue of Nature 1 has revealed a striking counter example to this rule. Figure 1: Structure of two ...

DNA is a complex molecule that consists of two strands coiled around each other to form a double helix structure. Comparison of a single ... which is then translated into proteins. This process is ...
