Comparative analyses of the four types of snoRNA clusters between chicken and human. Only one example is presented in each type of snoRNA cluster (A-D). The exons and snoRNA regions (not drawn to scale) are denoted by black and gray boxes, respectively. The snoRNA names, HGs and their chromosomal locations are indicated. The cognate snoRNAs between chicken and human are indicated by the same Roman numerals and linked by a line. The exon regions are indicated by Arabic numerals in order. The transcriptional direction is indicated by the arrowhead.
