Cell editors correct genetic errors

Volker Knoop, Elena Lesch, Bastian Oldenkott, Yingying Yang and Mareike Schallenberg-Rüdinger are investigating a gene correction mechanism in plants known as RNA editing. During this process, one of the RNA building blocks (cytidine, abbreviated C) is chemically converted into another (uridine, abbreviated U). Credit: © Simon Zumkeller/Uni Bonn Almost all …
