title: Isolation of simian virus 40 recombinants from cells infected with oligomeric forms of simian virus 40 deoxyribonucleic acid.
abstract: Oligomeric forms of simian virus 40 (SV40) deoxyribonucleic acid (DNA) were isolated from monkey kidney cells infected with two plaque morphology mutants of SV40. Recombinant, large clear-plaque-type SV40 was produced in cells productively infected with oligomeric forms of SV40 DNA.
