The Cell Cycle Cells grow, prepares for division, divides, and begin cycle again. IPMAT Stages of the cell cycle • • • • • Interphase Prophase Metaphase Anaphase Telophase Interphase • Most of the cell’s life time. • Chromosomes replicate. • Chromosomes are not visible under microscope. Prophase • 1st stage of mitosis. • Chromosomes become visible through a microscope. • Nuclear envelope breaks down. • Chromosomes attach to spindle fibers. Metaphase • Chromosomes line up in center of cell. • Chromosomes connected to spindle fiber at its centromere. Anaphase • Sister chromatids separate and are pulled to opposite sides of the cell. Telophase • New nuclear envelopes are formed around each set of chromosomes. Cytokinesis • Cytoplasm pinches off to form two new cells, each with its own nucleus.
