WebDec 8, 2024 · The genome of a eukaryotic organism is comprised of a supra-molecular complex of chromatin fibers and intricately folded three-dimensional (3D) structures. Chromosomal interactions and topological changes in response to the developmental and/or environmental stimuli affect gene expression. WebEach chromosome consists enormously long linear DNA molecule associated with proteins that fold and pack the fine thread of DNA into a more compact structure. [2] Commonly, many people think the structure of a chromosome is in an "X" shape. But this is only present when the cell divides.
