Question

Quizplus · Accepted Answer

Chromosomes are condensed into visible structures during cell division, specifically during the metaphase stage of mitosis or meiosis. During this phase, the chromosomes are at their most condensed and are visible with a light microscope. Outside of cell division, chromosomes are usually in the form of loosely arranged chromatin fibers and are not visible with a light microscope.
