Ei: exons, Li: linear splicing junction (for linear RNA). Ci: circular splicing junction (for circRNA). Two sets of isoforms of linear RNA and circRNA are shown on left and right sides. 3` in circular splicing junction is donor, while 5` is acceptor. All linear isoforms are sensitive to RNase R. Circular isoforms show no significant decrease in abundance after RNase R treatment
