For example, if 8% of the cells were in prophase and the cell cycle was 10 hours long, then prophase would last 8% of 10 hours, or 0.8 hours (48 minutes). Use percentages to estimate the duration of each phase of the cell cycle. s\u0026p versus moody\u0027s rating table

With the two nuclei already at opposite poles of the cell, the cell cytoplasm separates, and the cell pinches in the middle, ultimately leading to cleavage. In most cells, the mitotic spindle determines the site where the cell will begin to invaginate and split.
