Explanation:
Detailed explanation-1: -The spindle is a complex microtubule-based superstructure responsible for chromosome movement and segregation during mitosis and meiosis (McIntosh and Koonce 1989; Mitchison 1989a; Rieder 1991; Hyman and Karsenti 1996; Compton 2000).
Detailed explanation-2: -Spindle Fiber Formation They extend out microtubules that are used to pull the chromosomes (condensed DNA pairs) apart and to each side of the cell, allowing the two daughter cells to be completely identical. The spindle fibers begin to form during prophase of cell division.
