AbstractIn eukaryotes three major nuclear RNA Polymerases (Pols I, II and III) transcribe the genome. Pols II and III transcribe many different genes. Pol I has only one target from which it synthesizes the precursor for 3 of 4 ribosomal (r)RNAs accounting for up to 60 percent of total cellular RNA. Dedication of Pol I and its specific transcription factors to transcribe a single gene underlines the importance of rRNA synthesis. Research in Regensburg aims at understanding mechanism(s) of Pol I transcription.
