title: [Structuro-functional organization of the SV40 virus chromosome. IV. Specific organization of regulatory sequences of the SV40 genome in the mini-chromosome].
abstract: Using previously described technique of hybridization end-labeling, we analysed nucleosomal organization of the regulatory region of SV40 minichromosome. We showed that DNAase II, in spite of certain specificity observed on the naked DNA, cut the minichromosome in a highly specific manner with the major hypersensitive site inside the enhancer. This hypersensitivity and that to micrococcal nuclease were not found when the chromosome of mature SV40 virions was tested.
