Observe Figure 25.2(a) of your lab manual. The disc in the center of the plate is saturated with a chemical being tested for mutagenic properties. As you know, this chemical has mutagenic properties because there are numerous revertant colonies on the plate. The concentration of the test chemical is highest in areas closest to the disc, and lowest in areas furthest from the disc. Why aren’t there revertant colonies in areas where the test chemical (which causes the reversions) is the greatest?
A) In high concentrations the test chemical is toxic B) In high concentrations the test chemical causes DNA repair C) In high concentration the test chemical causes spontaneous mutations
