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.

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
WebThe theory accurately reproduces the experimental contact probability profiles for the mitotic chromosomes in HeLa and DT40 cells. The LE rate is smaller at the start of mitosis and increases as the cells approach metaphase. Condensin II-mediated mean loop size is about six times larger than loops because of condensin I.
WebChromosomes become more condensed and visually discrete. Each sister chromatid attaches to spindle microtubules at the centromere via a protein complex called the kinetochore.
