small ribosomal subunit “small” rRNA Large ribosomal subunit - contains 3 different rRNAs rRNA content of Ribosomes rRNA gene organization - similarities among all eukaryotes - genes in long tandem arrays separated by non-transcribed spacers - always arranged in same 5’ to 3’ order of 18S, 5.8S and 28S - pre-rRNAs genes code for transcribed spacers, which are removed “processome” - involved in processing pre-rRNAs Transcription unit Many RNA Pol I transcribing simultaneously
