Removal of histone H1 exposes linker DNA in chromatin to DNAse I
Molecular Biology Reports
|July 1, 1984
Abstract:
After removal of histone H1 about 40% of DNA in chromatin acquires the sensitivity of naked DNA to DNAse I. Digestion of H1-depleted chromatin with DNAse I leads to a qualitative change in the digestion pattern, generating DNA fragments of approx. 200 b.p. and multiples, similar to those obtained with micrococcal nuclease. Both effects are reversed upon reconstitution of purified H1 to H1-depleted chromatin.
