title: Nucleosome repeat lengths and columnar chromatin structure.
abstract: Thorough quantitative study of nucleosome repeat length (NRL) distributions, conducted in 1992 by J. Widom, resulted in a striking observation that the linker lengths between the nucleosomes are quantized. Comparison of the NRL average values with the MNase cut distances predicted from the hypothetical columnar structure of chromatin (this work) shows a close correspondence between the two. This strongly suggests that the NRL distribution, actually, reflects the dominant role of columnar chromatin structure common for all eukaryotes.
