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 ...

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 ...

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 ...

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 ...

The two strands of the DNA helix are unzipped ... the correct shape and becomes a protein. Peptide bonds form between the adjacent amino acids to finalise the structure.
