Most, if not all RNAs , are transcribed as precursors that require processing to gain functionality. Ribosomal RNAs ( rRNA ) from all organisms undergo both exo‐ and endonucleolytic processing. Also, in all organisms, rRNA processing occurs inside large preribosomal particles and is coupled to nucleotide modification, folding of the precursor rRNA (pre‐ rRNA ), and assembly of the ribosomal proteins (r‐proteins). In this review, we focus on the processing pathway of pre‐ rRNAs of cytoplasmic ribosomes in the yeast Saccharomyces cerevisiae , without doubt, the organism where this pathway is best characterized. We summarize the current understanding of the rRNA maturation process, particularly focusing on the pre‐ rRNA processing sites, the enzymes responsible for the cleavage or trimming reactions and the different mechanisms that monitor and regulate the pathway. Strikingly, the overall order of the various processing steps is reasonably well conserved in eukaryotes, perhaps reflecting common principles for orchestrating the concomitant events of pre‐ rRNA processing and ribosome assembly.
