- Anaphase: The kinetochore microtubules that make up the spindle begin to shorten, separating the sister chromatids from one another and drawing each to opposite poles of the cell. Polar microtubules assist in this process as they begin to lengthen and push the poles farther from each other. Why is this separation of chromatids necessary?arrow_forwardPraeuce problem Using the diagram from the Cell Cycle lesson, we can practice calculating a mitotic index. 1. Count the number of cells that are in ANY stage of mitosis (PMAT). 2. Count the total number of cells. 3. Use the Mitotic Index formula to calculate the mitotic index for this sample.
