Locus Overview

Systematic Name
Feature Type
multigene locus
Ribosomal DNA (rDNA); an approximately 1-2 Mb region on the right arm of chr. XII consisting of 100-200 tandem copies of a 9.1 kb repeat which contains the genes for 5S, 5.8S, 25S and 18S rRNAs (represented by the RDN37, RDN25, RDN18, RDN58, and RDN5 loci); a specific histone modification (H3K56ac) regulates RNA polymerase I transcription of the ribosomal DNA 1 2
