WebPurpose: High proliferation rate is a hallmark of cancer. The mitotic index is a useful and simple method for analysis of cell proliferation. However, the practical utility of mitotic … WebThe cell cycle. In eukaryotic cells, the cell cycle is divided into two major phases: interphase and mitosis (or the mitotic (M) phase). Interphase is the longest part of the cell cycle. This is when the cell grows and copies its DNA before moving into mitosis. During mitosis, chromosomes will align, separate, and move into new daughter cells.
