The effects of x radiation on the synthesis of nucleic acids were studied in Escherichia coli grown in a glucose mineral medium. The growth of bacteria irradiated with 16,000 r was observed to be slowed down when compared with controls. The synthesis of ribonucleic acid (RNA) took place in the irradiated cells without delay and at the same rate as growth but great changes were observed in the synthesis of desoxyribonucleic acids (DNA). The biosynthetic patterns were observed to depend on the method of chemical fractionation. After exposure to doses of 1000 r x radiation the growth and synthesis of both RNA and DNA were almost identical as in nonirradiated control cultures. Results are compared with published data.
