G7 cell cycle
The document discusses the cell cycle and cell division. It begins by defining key terms like cell cycle, interphase, and mitosis. It then outlines and describes the six main phases of the cell cycle: interphase consisting of G1, S, and G2 phases, mitosis which has prophase, metaphase, anaphase and telophase, and cytokinesis. During interphase, the cell grows and its DNA is copied in preparation for division. Mitosis involves the equal separation of chromosomes into two daughter cells, and cytokinesis separates the cytoplasmic contents to form two independent cells. The goals of the cell cycle are for growth, development, repair and reproduction through cell division.
