From: Stable intronic sequence RNAs (sisRNAs) are selected regions in introns with distinct properties
The sequences of sisRNAs have higher GC and TG content, while CpG poor compared to the genome. a-b The ratio of observed/expected (O/E) for the occurrence of dinucleotide (a) and trinucleotide (b) combinations in sisRNAs identified by refSeq genes (red) and by Ensembl genes (blue). c-e Boxplots show the GC% (c), CpG density (d) and CA/TG density (e) of the genome (green) compared to sisRNAs identified by refSeq (red) and Ensembl (blue) genes
