autoradiographic studies showed that more than 20 % of the cells in the infected fu-treated culture synthesized viral dna when less than 1 % had synthesized cellular dna , indicating that the synthesis of viral macromolecules proceeds in cells that do not synthesize cellular dna from the time of infection , and that viral dna synthesis proceeds independently of the host cell dna synthesis .
