Archaeal nucleosomes do not assemble on the ribosomal DNA operon. Profiles of the archaeal nucleosomes assembled by HTkA and HTkB in vivo in T. kodakarensis LC125 and LC124, respectively, and in vitro on a 10 Kbp region of the T. kodakarensis genome. As illustrated, this region encodes the 16S and 23S rRNA (rDNA operon; red arrows) and several protein-encoding flanking genes [34,39].
