Spo13 protects meiotic cohesin at centromeres in meiosis I
WebMitotic kinetochores are initially captured by dynamic microtubules via a ‘search-and-capture’ mechanism. The microtubule motor, dynein, is critical for kinetochore capture as it has been shown to transport microtubule-attached chromosomes towards the spindle pole during early mitosis. The microtubule-binding Ndc80 complex that is recruited to … WebVIDEO ANSWER: View, the answer to the pose is given.

Is the equatorial plate the same as the metaphase plate?
WebMetaphase. In metaphase, the microtubules pull on the chromosomes with equal force, and the chromosome moves to the center of the cell. Anaphase. The anaphase is marked by … WebIn contrast, oocytes can progress normally to metaphase I after superovulation but display precocious separation of sister chromatids, aneuploidy, and broken chromosomes at metaphase II. Spermatocytes undergo a developmental arrest during the early stages of meiotic prophase I, providing evidence for the role of RAD51C in early stages of RAD51 … Web20 nov. 2024 · Meiosis and mitosis both have a prophase, metaphase, anaphase, telophase and cytokinesis. In meiosis, prophase, metaphase, anaphase and telophase occur twice. The first round of division is special, but the second round is more like mitosis.
