The organelle that produces the spindle
The cellular spindle apparatus includes the spindle microtubules, associated proteins, which include kinesin and dynein molecular motors, condensed chromosomes, and any centrosomes or asters that may be present at the spindle poles depending on the cell type. The spindle apparatus is vaguely ellipsoid in cross Visa mer In cell biology, the spindle apparatus is 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, … Visa mer Attachment of microtubules to chromosomes is mediated by kinetochores, which actively monitor spindle formation and prevent premature Visa mer The guanine nucleotide exchange factor for the small GTPase Ran (Regulator of chromosome condensation 1 or RCC1) is attached to nucleosomes via core histones H2A and … Visa mer 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 of the duplicated genome, resulting in sister chromatids that are disentangled and … Visa mer In a properly formed mitotic spindle, bi-oriented chromosomes are aligned along the equator of the cell with spindle microtubules … Visa mer Spindle assembly is largely regulated by phosphorylation events catalyzed by mitotic kinases. Cyclin dependent kinase complexes (CDKs) are activated by mitotic cyclins, whose translation increases during mitosis. CDK1 (also called CDC2) is considered the main … Visa mer The completion of spindle formation is a crucial transition point in the cell cycle called the spindle assembly checkpoint. If chromosomes are … Visa mer Webb18 nov. 2024 · Spindle fibers are formed from microtubules with many accessory proteins which help guide the process of genetic division.
