WebApr 11, 2024 · Metaphase is a stage during the process of cell division (mitosis or meiosis). Normally, individual chromosomes are spread out in the cell nucleus. During metaphase, the nucleus dissolves and the cell’s … WebThe chromosomes begin to decondense and return to their “stringy” form. Cytokinesis, the division of the cytoplasm to form two new cells, overlaps with the final stages of mitosis. It may start in either anaphase or telophase, depending on the cell, and finishes shortly … During the mitotic (M) phase, the cell divides its copied DNA and cytoplasm to … A centromere is the central region of a chromosome itself, while the …

WebJul 17, 2024 · In metaphase II of meiosis, the following events occur: The chromosomes line up at the metaphase II plate at the cell's center. The kinetochore fibers of the sister chromatids point toward opposite poles. At the end of metaphase II of meiosis, the cell enters into anaphase II. Anaphase II Ed Reschke/Photolibrary/Getty Images WebEven though the aim of chromosomes during prometaphase is the same, namely biorientation and alignment, they can achieve this aim by different spatial paths that are mainly defined by the initial position of the chromosome with respect to the spindle during early prometaphase.
