A biologist has hypothesized that high concentrations of actinomycin D inhibit RNA synthesisin cells and thereby inhibit the production of proteins. An experiment conducted to test thistheory compared the RNA synthesis in cells treated with two concentrations of actinomycin D:0.6 and 0.7 micrograms per liter. Cells treated with the lower concentration (0.6) of actinomycinD yielded that 55 out of 70 developed normally whereas only 23 out of 70 appeared to develop normally for the higher concentration (0.7). Do these data indicate that the rate of normal RNAsynthesis is lower for cells exposed to the higher concentrations of actinomycin D?
