Linker DNA end-to-end distance is similar in H1-bound WT and gH3 nucleosomes. (A) FRET efficiency was determined for WT and gH3 nucleosomes containing Cy3 and Cy5 labels attached near the ends of the DNA (see Materials and Methods) in the absence or presence of H1, as indicated. (*), P < 0.05; NS, no significant difference. (B) Schematic describing changes in linker DNA end-to-end distance observed in (A).
