abstract = {Two physical models are considered to describe the
large-scale structure of chromatin in the nucleus of a
biological cell in the interphase state: a fractal globule
model and a logarithmic fractal model. Based on the
classification of fractal objects developed by the
small-angle neutron scattering (SANS) method, it is shown
that the fractal globule model does not satisfy the
experimental data on small-angle neutron scattering by the
nuclei of biological cells. Conversely, the logarithmic
fractal model well describes the experimental data on SANS
and, hence, provides a good approximation to describe the
large-scale structure of chromatin. The logarithmic fractal
model predicts that the nuclear space is exactly half-filled
with chromatin, and the second half consists of
interchromatin voids filled with nucleoplasma in which
various nuclear processes occur. Thus, two opposing trends
are balanced in the structural organization of chromatin: an
increase in the surface area of chromatin in the cell
nucleus (accessibility to external agents) and a decrease in
the volume occupied by chromatin (compactness of the
nucleus).},
