SSC MTS EXAM

Detailed explanation-1: -The mitotic spindle also begins to develop during prophase . As the cell’s two centrosomes move toward opposite poles, microtubules gradually assemble between them, forming the network that will later pull the duplicated chromosomes apart.

Detailed explanation-2: -In vertebrate somatic cells, the centrosome functions as the major microtubule-organizing center (MTOC), which splits and separates to form the poles of the mitotic spindle.

Detailed explanation-3: -The spindle starts to form during the prophase of mitosis. The spindles start to attach to the Kinetochores of centromeres of sister chromatids during Prometaphase. The first and longest phase of mitosis is prophase.
