Many proteins have been implicated genetically and biochemically in the assembly of eukaryotic ribosomes. Now, Kornprobst et al. show us how they are put together with a cryoEM structure of the 90S processome that initiates ribosome assembly, revealing the arrangement of U3 RNA and the several UTP complexes that form a chaperone-like structure around and within the developing 40S ribosomal subunit.
