Stimulation of DNA synthesis in mouse cell line 3T3 by Simian virus 40.

Abstract
We have investigated nucleic acid production during the early stages of transformation of 3T3 cells by SV40 virus. A stimulation of DNA synthesis was observed at 16-24 hr after infection. The nucleic acid homology studies demonstrated that: (1) most of the newly synthesized DNA was of host cell origin, and (2) viral DNA persisted up to 32 hr after infection and replicated to a very limited extent.
