Circrna formation mechanism

Circular RNA (or circRNA) is a type of single-stranded RNA which, unlike linear RNA, forms a covalently closed continuous loop. In circular RNA, the 3' and 5' ends normally present in an RNA molecule have been joined together. This feature confers numerous properties to circular RNA, many of which have only recently been identified. Many types of circular RNA arise from otherwise protein-coding genes. Some circular RNA has … WebApr 12, 2024 · Back-splicing involves the formation of a covalent link between a downstream splice-donor site and an upstream splice-acceptor site. Despite the fact that they are not produced through a back-splicing mechanism, viroids were the first circRNA molecules to be discovered more than 40 years ago .
