title: [Effect of the length of internucleosome regions of DNA on the conformation of chromatid fibrils].
abstract: Models of chromatin fibers structures with linear regions of linker DNA were analysed. Limitations put by end dimensions of linker DNA and nucleosomes are considered. Good agreement between the structural properties of model and real chromatin fibers was obtained. It has been shown that the models with three and more configurations of closely located nucleosomes have linker DNA of 19-53 base pairs length, which is characteristic of real chromatin of the majority of somatic cells.
