What have we learned about RNA structure and function so far? Although RNA is a single-stranded molecule, researchers soon discovered that it can form double-stranded structures, which are ...

Chemical formulae The chemical formula for a substance shows how many atoms of each element are present in a molecule, or the proportion of atoms of each element. The formula can be worked out ...

such as experiments testing structure-based predictions. We also expect to see more studies that focus on the integration of high resolution molecular structures into supramolecular complexes ...

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 ...
