Abstract
(32)P-Labeled SV40 DNA was treated sequentially with restricting endonucleases EcoRI and Hpa I, and the resulting four fragments of DNA were separated by gel electrophoresis. The kinetics of renaturation of each of the fragments and of complete SV40 DNA were measured in the presence of DNA extracted from the SVT2 line of SV40-transformed mouse cells. It was found that these cells contain about six copies of a segment of DNA which includes the early region of the SV40 genome, and about one copy of the late viral sequences. To map the region of the viral genome which is transcribed in SVT2 cells, separated strands of each of the four fragments were prepared and hybridized to total transformed cell RNA. Part of the E strands of the two DNA fragments (A and C) which span the early region of the SV40 genome were found to enter the hybrid.
