Exon position of circRNAs in the host gene. Exons of the parent transcripts were numbered. The number of the first an the last exon included in a circRNA is represented in the left (5’-end) and right (3’-end) panel, respectively. CircRNAs are stratified by (a) normalized circRNA expression into four groups (green to red with decreasing ratio) and (b) relative fold change between RNase R untreated and treated experiments (green to red with decreasing difference). As a reference, randomly selected exons in the control (gray) exhibit a higher number of second and third exons in a transcript just by chance
