snoRNA representation in the genome of platypus. (A) snoRNAs with corresponding paralogs distributed by cis- or trans-duplication (trans). (Red lettering) snoRNAs conserved in human. snoRNAs are grouped as CD-box snoRNAs, H/ACA-box snoRNAs, and snoRTE-H/ACAs, the last group was generated by retroposition. (B) Nonduplicated snoRNAs. (Oa) Experimentally identified snoRNAs; (bOa) snoRNAs identified computationally. Diverged snoRNAs (drift) show no canonical structural requirements necessary for function.
