By comparing the mitochondrial 15S rRNA sequences of four wildtype yeast strains together with their respective secondary structures, with those of the 16S-like ribosomal RNA from other organisms we detected two optional and two invariant AT-clusters. The origin of these clusters is discussed with respect to their roles as possible mobile elements.
