Pjg. Butler et Jo. Thomas, DINUCLEOSOMES SHOW COMPACTION BY IONIC-STRENGTH, CONSISTENT WITH BENDING OF LINKER DNA, Journal of Molecular Biology, 281(3), 1998, pp. 401-407
Nucleosome dimers from chicken erythrocytes show an ionic strength dep
endence of sedimentation coefficient similar to that of trimers, and i
ndicative of a degree of compaction over a range of low ionic strength
s. This is not easily reconciled with straight linkers but is consiste
nt with bending or kinking of the linker DNA. (C) 1998 Academic Press.
