Near the Golgi, there are 9,0 microtubule multiplets that produce microtubules. In order to sustain a dynamic movement process and for the centralized organization of chromosomes along the meiosis,plate, these microtubules bind to the kinetochores of chromosomes utilizing dyneins and kinesins.

During metaphase, chromosomes are organized over the metaphase plate with the help of microtubules released from complexes on various cell surfaces. Microtubules are continuously destroyed and rebuilt in a dynamic process until chromosomes are centrally organized.
