Ribonucleoproteins in Archaeal Pre-rRNA Processing and Modification
Figure 2
An example of a polycistronic rDNA locus in Archaea. (a) Linear representation of the genome organization of the rrn locus typical of the Euryarchaeotes. There are also various other combinations of operon organization (see text). (b) Secondary structure of pre-rRNA transcript in the Euryarchaeotes. Splicing occurs at arrow points to liberate the individual constituents from the polycistronic transcripts via an archaeal-specific mechanism. Only splice sites for individual rRNA components are included for simplicity. Adapted with permission from [11].
