Model of differences between C/D and H/ACA families. Box C/D snoRNA families (left part) are mostly small, typically with all members encoded in the same host gene, resulting from recombination as an evolutionary force, members display low abundance variability across tissues and at the same time more switches between tissues. Box H/ACA families (right part) are larger with members encoded in more than one host gene, as a result of retrotransposition and as a consequence, members display more abundance variability across tissues
