The mitotic regulator Cdc14 is shown to mediate transcriptional silencing of yeast ribosomal genes by preventing the nucleolar localization of a subunit of RNA polymerase I. If ribosomal transcription is not shut down, the presence of transcripts prevents the loading of condensin and blocks chromosome condensation and segregation.
