Step-by-step solution
Nucleosomes constitute the repeating unit of a structure in the nucleus called chromatin, thread-like stained (coloured) bodies seen in the nucleus. The nucleosomes in chromatin are seen as ‘beads-on-string’ structure when viewed under electron microscope (EM) (Figure 5.4 b). The beads-on-string structure in chromatin is packaged to form chromatin fibers that are further coiled and condensed at the metaphase stage of cell division to form chromosomes. The packaging of chromatin at higher level requires additional s
