WebOct 27, 2014 · Chromosomes are composed of thin chromatin threads called Chromatin fibers. These fibers undergo folding, coiling and supercoiling during prophase so that the chromosomes become progressively thicker and smaller. Therefore, chromosomes become readily observable under light microscope. WebThere are four main stages of mitosis: prophase, metaphase, anaphase, and telophase. The longest stage of mitosis is typically metaphase, which is characterized by the alignment of the chromosomes at the equatorial plane of the cell. During prophase, the first stage of mitosis, the cell's nucleolus disappears and the nuclear envelope breaks down. five force analysis nike
