From: The exon context and distribution of Euascomycetes rRNA spliceosomal introns

Logo analysis of 50 nt upstream and downstream of insertion sites of 43 different spliceosomal rRNA introns. The information content of the 2 Gs of the intron proto-splice site is shown as is a line at p = 0.05 (95% quantile) that is based on simulations using random sequence data. This exon region contains a total of 6.91 bits of information.
