Researchers at St. Jude Children's Research Hospital discovered that smaller sub-compartments within the nucleolus form to finish the final steps of ribosome assembly. These sub-compartments lock major ribosome building blocks together until they are assembled, preventing a key protein from associating with them prematurely.
