Abstract
Three trends are seen in the organization of ribosomal DNA genes during evolution: 1) gradual separation and separability of the regulation of transcription of 5S and larger subunit rRNAs; 2) retention of a transcription unit containing both large and small rRNAs; and 3) clustering of genes for both 5S and 18S-28S rDNAs, with the possible association of other 'non-rDNA' in the clusters of 18S-28S rDNA genes by the time mammals evolve.Mesh：
