Cell Cycle Cell Cycle—the sequence of growth and division of a cell. It is a cycle b/c it repeats itself over and over. Stages of the cell cycle Mitosis G2 Phase S Phase G1 Phase Interphase—longest period of cell cycle. Includes 3 parts: G1— Rapid protein synthesis and cell growth. Longest and most variable part of the cell cycle. Chromosomes are not visible in the nucleus. S stage— chromosomes are replicated in the nucleus. Chromosomes shorten and coil, become visible. G2— proteins needed for cell division (mitosis) are synthesized. Cell organizes for mitosis. Chromosomes continue to coil, are very visible. Mitosis (M phase)—actual division process of the cell. Shortest stage of the cycle. End result: two identical daughter cells formed.
