The length of this structure is affected by Kar3p 
The length of this structure is affected by Kar3p and Cin8p mutations, and this structure forms via abi-orientation mechanism. The formation of this structure requires Survivin activation of the Aurora Akinase. CENP-E- Bub1, and Mad2 are among the proteins involved in this structure's namesakeassembly checkpoint. This structure, whose formation is inhibited by vinca alkaloids, requires theprotein NuMA to form, which is why its formation is coupled to the degradation of the (*) nuclearmembrane. One side of this structures' fibers attaches to kinetochores, while the other side attaches togamma-ring complexes on the centrosome. For 10 points, name this structure which contains an arrayof microtubules, which are responsible for moving chromosomes apart during mitosis.
