<p>some taxonomically restricted lineages, and mediate thousands of edits. Another taxonomically restricted case of a different form of RNA editing system is found in land plants. In kinetoplastids, RNA editing involves the addition of thousands of nucleotides and deletion of several hundreds. However, the necessity of this highly complex system is questionable. The large majority of organisms do not rely on RNA editing systems, and in the ones that do have it, the need for it is unclear as the optimal solution would be for the DNA sequence to not</p><p>
