To sketch and explain: A favored model that explains the mechanism of polar movement of chromosomes in which microtubules shorten, generate force, and yet remain firmly attached to the kinetochore of the chromosome. Concept introduction: The sister chromatids have centromere to which the kinetochore complexes are bound. Thekinetochore is a disc-shaped protein. Kinetochore complexes bind to the microtubule and move along them by depolymerizing them. The depolymerization involves release of energy that helps them to slide along a microtubule.
