Zooming in on a ribozyme structure (IMAGE) DOE/SLAC National Accelerator Laboratory Caption Detail of the molecular structure of a ribozyme, or catalytic RNA, from a one-celled organism called Tetrahymena that lives in pond scum. Scientists at SLAC and Stanford have solved the 3D structure of this ribozyme and other RNA-only molecules with unprecedented speed, accuracy and resolution with a system called Ribosolve that combines computer software with cryogenic electron microscopy (cryo-EM.)
