متن کاملNMR Hits the Big Time
When it comes to structural biology, bigger really is better. Most biological processes are performed by enormous multicomponent complexes, such as the ribosome. To solve the structures of these monsters, biologists traditionally have used two different but complementary techniques, nuclear magnetic resonance (NMR) and X-ray crystallography. They have had considerable success using the latter t...
متن کاملMeiosis: MeiRNA hits the spot
