How long would it take for 99 of the iodine-131 produced a nuclear explosion to disappear. During prophase the nucleus disappears spindle fibers form and DNA condenses into chromosomes sister chromatids. Pin On Biology Articles Period during which a cell carries out its usual metabolic activities. . Division of the. One kinetochore forms per chromosome rather than one per chromatid and the chromosomes attached to spindle fibers begin to move. The nuclear envelope and nucleoli disappear during the prophase of mitosis. During prophase the chromosomes separate from one another and so the nucleolus disappears. The half-life of iodine-131 is 802 days. The nuclear membrane is absent during the entire phase. Prophase metaphase anaphase and telophase. The nuclear membrane has to be taken out of the way before metaphase so that the chromosomes can move out of the confines of the nucleus. The nuclear membrane and nu...
