Abstract | The distribution patterns of shared short repetitive motifs in the expansion segments of the large subunit rRNA genes of different species show that these segments are coevolving as a set and that in two examined vertebrate species the RNA secondary structures are conserved as a consequence of runs of motifs in one region being compensated by complementary motifs in another. These unusual processes, involving replication-slippage, have implications for the evolution of ribosomal RNA and for the use of the rDNA multigene family as a 'molecular clock' for assessing relationships between species. | |
