Eukaryotic ribosome biogenesis involves a plethora of ribosome-assembly factors, and their temporal order of association with preribosomal RNA is largely unknown. By using Saccharomyces cerevisiae as a model organism, we developed a system that recapitulates and arrests ribosome assembly at early stages, thus providing in vivo snapshots of nascent preribosomal particles. Here we report the stage-specific order in which 70 ribosome-assembly factors associate with preribosomal RNA domains, thereby forming the 6-MDa small-subunit processome.
