The Cell Cycle and Mitosis

Master the cell cycle and mitosis! Quiz yourself on stages, chromosomes, and cell division.

What are reasons our body cells can go through the cell cycle and mitosis?(select THREE in total) growth repair tissue damage sexual reproduction (babies) replace worn out cells human cloning CLICK HERE FOR MORE INFO to help fill this out!Label the chromosome with the correct terms. Word bank: centromere, chromosome, homologous chromosomes, sister chromatids chromosome centromere sister chromatids homologous chromosomes Match the definition with the correct term. Tightly coiled genetic information that appears during prophase. chromosome Doubled genetic information held together by a centromere. Described as "sisters". chromatid unwound DNA chromatin Match the stage of cell cycle with the correct definition. Interphase the "inbetween" period before division. When normal cell activity occurs. Made of three stages: G1, S, G2 Mitosis Nucleus divides into two. Four stages (PMAT) Cytokinesis Final cell division phase; cell plate (in plants) or cleavage furrow (in animals) divide cytoplasm. Two identical cells as result. Use the diagram to label the parts of the cell cycle. A [name for phases B-D] = InterphaseB = G1C = SD = G2E = ProphaseF = MetaphaseG = AnaphaseH = TelophaseI [name for phases E-H] = MitosisJ = Cytokinesis Match the stages of INTERPHASE with the correct definition. Gap 1 (G1) cell grows in size Synthesis (S) DNA is replicated Gap 2 (G2) Cell prepares to divide Use the image of MITOSIS to answer the questions below. This image is shuffled and the stages are NOT in order. A = ProphaseB = TelophaseC = MetaphaseD = InterphaseE = AnaphaseF = [this is a phase called "prometaphase", which occurs between prophase and metaphase]. Match the phases of mitosis with the correct definition. prophase nucleus disappears; centrioles appear; chromatin packed into chromosomes metaphase chromosomes line up in middle of cell anaphase chromosomes begin to separate; sister chromatids are pulled apart telophase two new nuclei form How is mitosis different from cytokinesis? mitosis divides the cytoplasm, cytokinesis divides the nucleus mitosis divides the nucleus; cytokinesis divides the cytoplasm cytokinesis happens first; mitosis happens second Sort the following according to which phase they describe of mitosis. Prophase chromatin is tightly wound into chromosomes Nuclear membrane breaks down spindle fibers are formed and centrioles appear Metaphase chromosomes line up in the middle of the cell spindle fibers help push chromosomes to middle of cell spindle fibers elongate (grow) Anaphase sister chromatids are pulled apart spindle fibers pull chromosomes to opposite ends of the cell, towards centrioles spindle fibers get shorter Telophase Two nuclei are formed chromosomes begin to unwind, back into chromatin spindle fibers disappear one complete set of chromosomes are in each new nucleus The daughter cells' DNA is _ the parent cell's DNA. identical to different from half the amount of If a cell has 24 chromosomes and does mitosis, how many chromosomes will each new daughter cell have? 12 24 48
