Step-by-step solution
DNA is wrapped histone proteins to form beads like structure called nucleosomes. This structure is further condensed to fit in a coiled helical structure called solenoid that on folding forms the chromatin fibre. Nucleosome forms the structural unit of chromatin fibre. Microtubules found in the cytoplasm of eukaryotic cells are made of polymers of protein, tubulin. Microtubules help with the structure and shape of the cell. Tight junctions are a type of cell junctions found in epithelial tissue that help to stop su
