| Abstract: | Genes of box C/D small nucleolar RNAs (snoRNAs) were searched for in the genomes of members of all classes of vertebrates that do not belong to placental mammals. A tendency for an increase in the number of copies of snoRNA genes was observed in such vertebrates. This trend was most pronounced in anamnia (amphibians and fish). Box C mutations were found in 14 snoRNAs in all gene copies among all species studied. The role of the described events is discussed. |
