Vedclass · Answer

(B) : In metaphase,chromosomes consisting of two sister chromatids get arranged at the equator. Discontinuous fibers radiate out from two spindle poles and get connected to the disc-shaped structure at the surface of the centromere called kinetochores. These are known as chromosome fibers or tractile fibrils. $A$ kinetochore is a complex protein structure that is analogous to a ring for the microtubule hook; it is the point where microtubules attach themselves.
