Many of the events of mitosis depend on mitotic spindle fibers which begin to form in the ____ during prophase
A
nucleus
B
cytoplasm
C
cell membrane
Explanation: 

Detailed explanation-1: -Several events during the process of mitosis depend on the mitotic spindle, which forms in the cytoplasm during prophase. The mitotic spindle is a structure that is composed of fibers made from microtubules and proteins. Microtubules are the rope-like components of the cytoskeleton.

Detailed explanation-2: -Spindle. The spindle starts to form during prophase of mitosis. Kinetochores on the spindle attach to the centromeres of sister chromatids.

Detailed explanation-3: -Metaphase follows prophase. During metaphase, the chromosomes align in the center of the cell at the equatorial plate and the spindle fibers attach to the centromeres of the chromosomes.
