Fig 1. General feature of the circRNA candidates.
(A) Genomic locations of the circRNAs. The backsplice site was predominantly located at CDS-only and intergenic-only. (B) Exon number distributions of circRNAs and their parent genes. (C) Length distributions of circRNAs and their parent genes. (D) Length distributions of back-spliced exons corresponding to different numbers of exons.
