Virus genome integration as a function of the host cell genome replicative cycle.
Mouse 3T3 cells were grown and synchronized in monolayer with the double thymidine block. Their infection with SV40 took place continuously during the cellular cycle. However, integration of viral DNA into host cell DNA occurred preferentially during the S phase. Phase G1 appeared to be necessary for virus-cell DNA recombination in S phase. Phase G2 did not alter the stability of the integrated viral genome.
