摘要: We propose an idea how the helical pattern of charges on surface DNA can affect electrostatic interactions nucleosome core particles in their columnar and crystalline phases as well chromatin. For bilayers nucleosomes, we suggest that mutual azimuthal orientations neighbouring NCPs are quantized with angle ≈π/4. a similar mechanism DNA-mediated inter-nucleosome might stabilize new chromatin-like bundled nucleosomes which have not yet been observed.
