It has been shown by a modified DNA-RNA hybridization technique that the nuclei of cells transformed by either polyoma virus or SV40 contain viral DNA.1 This method employs RNA synthesized in vitro with form I viral DNA2–4 and E. coli RNA polymerase. The number of viral DNA equivalents per cell varies from 5 to 60, depending on the cell line. In this communication, we will report on the physical state of the viral DNA in SV3T3 cells, an SV40-transformed cell line that contains 20 SV40 DNA equivalents per cell.
