Superfast insights into cellular events

In the same way that a single piece of a puzzle fits into the whole, the molecule hypoxanthine binds to a ribonucleic acid (RNA) chain, which then changes its three-dimensional shape within a second and in so doing triggers new processes in the cell. Thanks to an improved method, researchers are now able to follow almost inconceivably tiny structural changes in cells as they progress-both in terms of time as well as space. The research group led by Professor Harald Schwalbe from the Center for Biomolecular Magnetic Resonance (BMRZ) at Goethe University has succeeded, together with researchers from Israel, in accelerating a hundred thousand-fold the nuclear magnetic resonance (NMR) method for investigating RNA.
