Abstract excerpt
The umuDC operons of both Salmonella typhimurium and Escherichia coli encode proteins which are essential for mutagenesis following exposure to ultraviolet radiation or a variety of chemicals. However S. typhimurium is less mutable and its umu operon appears to be less active for reasons that are...
