since pool size measurements indicated that both deoxyuridine triphosphate and deoxythymidine triphosphate pools were markedly elevated in dut mutants , the reduced growth rate of dut ung cells apparently was due to the actual presence of uracil in the dna , rather than to a deficiency of deoxyuridine triphosphate and deoxyribosylthymine triphosphate for dna synthesis .
