Fig. 1From: Circular RNAs in cancer: new insights into functions and implications in ovarian cancerThe kind of biogenesis of circRNAs: (a) Standard splicing (conventional linear splicing); (b) circRNAs is generated by a process called, Backsplicing: this splicing lead to creating 1) exonic circRNA that can make two forms including single exon circRNA and multiple exon circRNA, 2) Exonic-Intronic circRNA and 3) Intronic circRNABack to article page
