Orientation of nucleosomes and linker DNA in calf thymus chromatin determined by photochemical dichroism.

S Mitra, D Sen, D M Crothers.   

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.
