this conclusion is based on the following observations : ( i ) transcriptional complexes isolated by sarkosyl and by hypotonic leaching ( minichromosomes ) from nuclei of cells infected with sv40 as well as intact nuclei were pulse labeled in vitro with [ alpha-32p ] tup and were observed to synthesize short rna transcripts that hybridized predominantly to a sv40 dna fragment spanning between 0.67 and 0.76 map units .
