Heinz Lüneburgntal mutagenesis by a pure chemical agent was first achieved by Auerbach and Robson (1944, 1946) and a variety of such agents are now known. Their mechanisms of action appear to be fairly well understood as consisting of expressible heritable changes in the molecular structure of the genetic materia
