WebThe flanking introns of the circRNAs generated are not only devoid of rolling circle repeats but are highly enriched with satellite repeats compared to other Drosophila introns (Figure 6A–C). In addition to satellite enrichment, these introns were more enriched in LINEs with a bias of upstream enrichment compared to the downstream introns.
