The roles of H1, the histone core and DNA length in the unfolding of nucleosomes at low ionic strength.
Calf thymus nucleosomes exhibit two different and independent hydrodynamic responses to diminishing salt concentration. One change is gradual over the range 40 to 0.2 mM Na+ and is accompanied by decreases in contact-site cross-linking efficiency. The other change is abrupt, being centered between 1...
