Abstract excerpt
When populations of cells are subjected to nonlethal selection, mutations arise in the absence of cell division, a phenomenon that has been called "adaptive mutation." In a strain of Escherichia coli that cannot metabolize lactose (Lac-) but that reverts to lactose utilization (Lac+) when lactose is its sole energy and carbon source, the mutational process consists of two components. (1) A highly efficient,...
