Name ____________________________________ Period _____ Date _____________________ Notes - Cell cycle and Mitosis 1) _______________________ is the time between cell division where the cell grows to full size, duplicates its ___________ and ________________ 2) The 3 (4) stages of Interphase are _______, ________, _______ and __________ 3) Cell cycle diagram 4) G1 Phase. – G = ____________. Cells ______________ to normal size and _________ are made. 5) G0 phase – Is the ____________________ Phase. The cell is _____________ during this phase and undergoes normal _____________________________ while resting. Cells that skip this phase can become ______________________ growing _________________ 6) Check points – Places where cell checks itself for _______________ before proceeding. _____________ bypasses the checkpoints 7) S Phase – S = ________________________ Where DNA is ________________ or _____________ in preparation for cell _____________________ 8) Once a cell enters the S phase it is committed to g through ____________ ____________ (the point of ___________________________) 9) G2 Phase – G = _________________________ Cells grow larger in preparation for ______________ ___________________ 10)Cell Division – The way a cell __________________ itself. There are 2 steps. ______________ followed by ________________ 11)M phase = _______________________ The division of the _____________ DNA forms into___________________. Chromosomes with identical pairs move to _____________ sides of the cell and a new ______________ _____________ forms around each set of chromosomes 12)Chromosomes = _______________________ __________________________ appear only during ___________________ 13) Label Stages of Mitosis label parts 1) Prophase – Cell begins mitosis. DNA coils up forming chromosomes. Spindle fibers form. Centrioles appear 2) Metaphase – Chromosomes line up along center. Centrioles migrate to poles. Spindle fibers attach to Chromatids 3) Anaphase – Spindle fibers pull duplicate Chromatids apart. Chromatids migrate to opposite poles 4) Telophase – Chromatids gather together on separate sides. Nuclear membrane forms around chromosomes making 2 separate nuclei. Cell membrane starts to pinch together 5) Cytokinesis = C phase. Division of the cytoplasm and organelles between the cells. The cell membrane closes off each cell. 2 new daughter cells form, each an identical copy of parent cell. But smaller • Interphase AGAIN. Each daughter cell enters interphase, so it can ____________, ______________ and be a normal cell
