WebbThe 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. WebbThe cell cycle is a series of events that take place in a cell leading to duplication of its DNA and division of cytoplasm & organelles to produce two daughter cells. In other words, the cell cycle is an ordered series of events that involve cell growth & cell division to produces two new daughter cells. Although cell division occurs in all ...
