WebJul 1, 2024 · Mitotic spindles are composed of three main types of dynamic microtubule: (i) astral microtubules that are generated from the MTOC and extending towards the cell cortex ( Reinsch and Gönczy, 1998 ); (ii) interpolar microtubules that overlap at the midzone with antiparallel orientation ( Cai et al., 2009b; Hentrich and Surrey, 2010 ); (iii) … WebNov 10, 2015 · Here, we discuss our recent finding that a size-exclusion spindle envelope promotes mitotic fidelity in Drosophila cells in light of distinct spindle assembly …
Mitotic Spindle Assembly in Land Plants: Molecules and Mechanisms
WebJul 25, 2016 · The mitotic spindle performs the task of physically dividing the genetic material between the newly formed daughter cells. To achieve this, bundles of microtubules and associated proteins orchestrate forces that spatially organize and then separate the chromosomes. In the classic view of the spindle, the kinetochore microtubules (k-fibers) … WebAnother mechanism that controls APC activity is the spindle assembly checkpoint (SAC), which is activated when chromosomes are not properly attached to the mit otic spindle. Activation of the SAC leads to the formation of the mitotic checkpoint complex (MCC) that binds to the APC activator Cdc20, preventing degrada- spur monday specials
