The ribosome translates the DNA code into life

The 2009 year's Nobel Prize in Chemistry awards Venkatraman Ramakrishnan, Thomas A. Steitz and Ada E. Yonath for having showed what the ribosome looks like and how it functions at the atomic level. All three have used a method called X-ray crystallography to map the position for each and every one of the hundreds of thousands of atoms that make up the ribosome.

Inside every cell in all organisms, there are DNA molecules. They contain the blueprints for how a human being, a plant or a bacterium, looks and functions. But the DNA molecule is passive. If there was nothing else, there would be no life.

NMR: To understand, we need to see

Kurt Wüthrich had an idea for how to find out which peaks correspond to which atoms. His method is called sequential assignment. It involves starting with a signal from a known atomic nucleus and then finding the nucleus in the peptide chain that is signalling that it is a neighbour of the first. Wüthrich matched each signal successively with its atom. With a similar method, which senses the distance between nuclei, he then determined a large number of pairwise distances in the protein, which gave the three-dimensional structure of that protein.
