The term ‘RNA editing’ describes a variety of mechanistically unrelated biochemical activities that alter RNA molecules after transcription by addition, deletion or substitution of nucleotides. A three-stage model, illustrated by specific examples, can explain in a general way how RNA-editing systems might arise and become fixed.
