Webb12 nov. 2024 · During mitosis, the spindle fibers are called the mitotic spindle. Meanwhile, during meiosis, the spindle fibers are referred to as the meiotic spindle. At the beginning … WebbMitotic 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 …

However, the FtsZ protein that plays such a vital role in prokaryotic cytokinesis is structurally and functionally very similar to tubulin, the building block of the microtubules that make up the mitotic spindle fibers that are necessary for eukaryotes.
WebbM.A. Hultén, in Brenner's Encyclopedia of Genetics (Second Edition), 2013 Role in Mitotic Spindle Checkpoint. Kinetochores are important elements of a mitotic checkpoint. Failure of kinetochores to bind to spindle microtubules, or incorrect association such as when both sister kinetochores attach to microtubules from the same spindle pole, results in mitotic … Webb30 sep. 2024 · Spindle fibers are part of a spindle apparatus that moves chromosomes during mitosis and meiosis to ensure even chromosome distribution between daughter cells. The spindle apparatus of a cell is comprised of spindle fibers, motor proteins, chromosomes, and, in some animal cells, microtubule arrays called asters.
