Abstract
Eukaryotic cells contain several hundred copies of the ribosomal RNA genes co-existing in two distinct chromatin conformationsan active conformation permissive to transcription and an inactive conformation refractive to transcription. Whereas silencing of rRNA gene transcription has been partly uncovered, the epigenetic mechanisms leading to the active rRNA gene chromatin structure are less well understood. Here we discuss recent studies addressing the local and higher order structure of active rRNA gene chromatin.
