In cell biology, the spindle apparatus refers to the cytoskeletal structure of eukaryotic cells that forms during cell division to separate sister chromatids between daughter cells. It is referred to as the mitotic spindle during mitosis, a process that produces genetically identical daughter cells, or the meiotic spindle … Zobacz więcej Attachment of microtubules to chromosomes is mediated by kinetochores, which actively monitor spindle formation and prevent premature anaphase onset. Microtubule polymerization and depolymerization … Zobacz więcej In a properly formed mitotic spindle, bi-oriented chromosomes are aligned along the equator of the cell with spindle microtubules oriented roughly perpendicular to the chromosomes, their plus-ends embedded in kinetochores and their minus … Zobacz więcej By the end of DNA replication, sister chromatids are bound together in an amorphous mass of tangled DNA and protein. Mitotic entry triggers a dramatic reorganization … Zobacz więcej Cell division orientation is of major importance for tissue architecture, cell fates and morphogenesis. Cells tend to divide along … Zobacz więcej The guanine nucleotide exchange factor for the small GTPase Ran (Regulator of chromosome condensation 1 or RCC1) is attached to … Zobacz więcej Spindle assembly is largely regulated by phosphorylation events catalyzed by mitotic kinases. Cyclin dependent kinase complexes … Zobacz więcej The completion of spindle formation is a crucial transition point in the cell cycle called the spindle assembly checkpoint. If chromosomes are not properly attached to the mitotic spindle by the time of this checkpoint, the onset of anaphase will be delayed. … Zobacz więcej Witryna13 mar 2012 · Learn about mitotic spindles, their role in mitosis, and why they are necessary for cell reproduction.
