when viral growth in tc-7 cells is compared with that in the simian virus 40 ( sv40 ) transformed cv-1 line c6 some mutants of sv40 deleted between 0.54 and 0.59 on the standard map ( dl 54/59 mutants ) give relative bursts similar to those of wild-type strain 776 , whereas others grow markedly poorer in the untransformed cell .
