The nuclear membrane disappears in metaphase
WebA unique feature of of nucleus is that it disassembles and re-forms each time most single divide. At the ab a my, the chromosomes compaction, the nucleolus disappears, and the nuclear envelope breaks down, resulting in an release of most of an contents of the nucleus at the cytoplasmic. At the end of mitosis, the process is reversed: The clastogenic … WebIn prophase the chromosomes condense, mitotic spindles begin to form, and the nuclear envelope starts to disappear. Pro-metaphase. In this stage the nuclear envelope disappears, and the spindle microtubules attach to the kinetochores. Metaphase. During metaphase the align single file on the metaphase plate. Anaphase

WebDuring karyokinesis the nuclear membrane disappears. Nuclear membrane starts disappearing at the start of mitosis and by the late prophase it disappears completely along with the major cell organelles. The nuclear membrane disappears presumably to allow more space for karyokinesis and proper separation of chromatids. WebJan 17, 2024 · The nuclear envelope breaks down and spindle fibers form at opposite poles of the cell. Metaphase: In this stage, the nuclear membrane disappears completely. The spindle fully develops and the chromosomes align at the metaphase plate (a plane that is equally distant from the two poles).
