Stresses that could be generated by chromatin expansion against contraining features. (A and B) Compression stress along the DNA/chromatin fiber can destabilize DNA (A) or promote a more compact fiber configuration (B). (C) Interchromatin pushing produces opposing forces for separation and interface compression. (D) Linear/loop axis array (Left) and prophase configuration with cooriented sister arrays (Right). (E) Changes in axis status predicted from pushing forces between adjacent chromatin loops.
