  1. cDNA hybridization after growth in methionine or MTR. The conditions are chosen to display roughly identical values for most genes in both conditions. The values obtained for the arginine operons described in the text are shown here. They indicate a higher expression in methionine as compared to MTR, all things being otherwise equal. Each spot in the experiment is referred to as a and b.
