Abstract
In arginine-deprived cells infected with simian virus 40 (SV40), both viral DNA and viral structural proteins were synthesized but infectious virus was not produced. The syntheses of cellular DNA, thymidine kinase and DNA polymerase were induced in virus-infected cells deprived of arginine but the maximum rate of synthesis of these enzymes occurred much later than that in infected cells incubated in the presence of arginine.
