the observation of asymmetric decondensation of heterochromatin by hoechst 33258 after budr incorporation for one cell cycle , the association of a-t rich satellite dna to mouse heterochromatin , and available data on the specific binding of hoechst 33258 to a-t base pairs of dna and on the higher affinity of the compound to budr substituted dna than to ordinary dna implied that the binding of hoechst 33258 molecules to a-t rich satellite dna is the cause of heterochromatin decondensation .
