In eukaryotic cells, circular RNAs (circRNAs) are produced primarily by back-splicing events of pre-mRNAs 1. Nascent pre-mRNAs are produced by RNA polymerase II and undergo multiple processing steps ...
Although the genetic material of most living organisms is DNA, various self-replicating agents rely instead on RNA, including RNA viruses and viroids, which are infectious RNA molecules that are ...
