on analysis in dodecyl sulphate/polyacrylamide gels poly ( h1 ) gives a striking pattern of alternating strong and weak bands which have been shown , by the use of cleavable cross-linked reagents and two-dimensional gel electrophoresis , to arise respectively from h1 homopolymers and h1 polymers linked to the nucleosome core histones .
