Vedclass · Answer

(D) During the interphase stage of the cell cycle,the genetic material exists in the form of a loose,thread-like network known as chromatin. In a light microscope,individual chromosomes are not visible because they are not yet condensed. However,certain regions of the chromatin,known as heterochromatin,are more densely packed and stain more intensely,making them visible as distinct dark-staining patches within the nucleus. Nucleosomes and centromeres are structures that require higher resolution (like electron microscopy) or specific staining techniques to be clearly identified.
