The tandem array of ribosomal DNA (rDNA) in Saccharomyces cerevisiae is subjected to transcriptional silencing of RNA polymerase II-transcribed genes. This form of silencing depends on SIR2 and has been tightly linked to the suppression of rDNA recombination and the control of cellular lifespan. Paradoxically, rDNA silencing takes place in the context of an(More)
