The assembly of a eucaryotic ribosome requires the synthesis of four ribosomal ribonucleic acid (RNA) molecules and more than 75 ribosomal proteins. It utilizes all three RNA polymerases; it requires the cooperation of the nucleus and the cytoplasm, the processing of RNA, and the specific interaction of RNA and protein molecules. It is carried out efficiently and is exquisitely sensitive to the needs of the cell. Our current understanding of this process in the genetically tractable yeast Saccharomyces cerevisiae is reviewed.
