We have recently reported that certain core histone-DNA contacts are altered in
nucleosomes during chromatin unfolding (Usachenko, SI, Gavin IM, and Bavykin, SG (1996) …

We have previously shown that the sequential arrangement of histone-DNA contacts is
essentially the same in the nucleosomal core of sea urchin sperm nuclei, where chromatin is …

For several years we have been interested in chromatin structure and in the part it plays in
transcriptional activity. Although it is clear that the nucleosome serves to fold DNA into a …

We describe studies of histone—DNA contacts in the nucleosome using the method of
covalent zero length protein—DNA crosslinking. These studies show that in intact nuclei …

The kinetics of the chromatin core particle reassembly reaction in solution were
quantitatively studied under conditions such that nucleohistone aggregation did not occur …

Over the last several years biochemical and genetic studies have confirmed the importance
of chromatin structures in regulating gene expression (reviewed in Kornberg and Larch …
