Circrna formation mechanism
WebDec 6, 2024 · CircRNAs are notable for their continuous closed loop structure, named a ‘back-splicing’ structure, which is primarily formed via the junction of a downstream 3′ splice site with an upstream 5′ splice site (head-to-tail splicing) [ 3 ]. Thus, these structures can resist exonucleolytic degradation by RNase R. WebDec 31, 2024 · Abstract. Circular RNA (circRNA) is a non-coding molecule produced through alternative splicing of one or more exons of a gene in the presence of an RNA …
