Genomic organization of C. elegans H/ACA snoRNAs. (A) Intron length distribution of H/ACA host genes compared to all C. elegans protein-coding genes. Note that the left scale refers to the counts of host gene introns, while the right scale refers to the counts of all introns. (C1–C5) The intron length categories (see the text for details). (B) Examples showing structure of a compact gene and a noncompact gene (from WormBase).
