Molecular mechanisms of ribozymes Some of the ... would be otherwise impossible to visualize experimentally. The crystal structure of the hairpin ribozyme–vanadate complex, when compared with ...

This particle diagram represents water or, to use its chemical formula, H₂O which is a compound of the elements hydrogen and oxygen. In one molecule of water, there are two hydrogen atoms and ...

Many of the familiar properties of water that result in its behavior in soils can be directly related to its molecular structure. Aa Aa Aa "Water is the driving force of all nature." - Leonardo da ...

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 ...
