Elastic torsional strain in DNA within a fraction of SV40 minichromosomes: relation to transcriptionally active chromatin.
After treatment of SV40 minichromosomes with DNA topoisomerase I, the superhelicity in the bulk of the DNA extracted from minichromosomes is known to remain unchanged. However, we found that the DNA extracted from a small fraction of SV40 minichromosomes (2-5%), was almost completely relaxed, and co...
