Abstract excerpt

More than one copy of rRNA operons, which code for both the small-subunit (SSU) and large-subunit (LSU) rRNA, are often found in prokaryotes. It is generally assumed that all rRNA operons within a single cell are almost identical. A notable exception is the extremely halophilic archaeal genus Haloarcula, most species of which are known to harbor highly divergent rRNA operons that differ at approximately 5% of the...
