Orientation of nucleosomes and linker DNA in calf thymus chromatin determined by photochemical dichroism
S Mitra et al. Nature. 1984 Mar.
Abstract
The dichroism for photochemical attachment of a psoralen derivative to Mg2+-stabilized chromatin fibres is used to deduce the orientation of nucleosomal disks and linker DNA in the 30-nm fibre. The new technique of photochemical electric dichroism should have general applicability to problems of nucleic acid organization in cellular subunits and viruses.
