Circrna vector topology
WebDec 1, 2024 · CircRNA translation 1. Introduction Circular RNAs (circRNAs) are a class of single-stranded RNAs distinguished by their covalently-closed topology. In the decades closely following their discovery, circRNAs were presumed to be rare, functionally inert byproducts of aberrant splicing [1]. WebFeb 15, 2024 · Properties of circRNAs. CircRNAs are produced from precursor mRNA and are derived from canonical splice site. CircRNA biogenesis can compete with the maturation of its linear counterpart by linking 3′ splice site to a downstream 5′ splice site [].CircRNAs can be classified into three different types based on the type of sequence they contain: …
