2nd Period - Cell Cycle and Mitosis Review

The diagram below shows the process of the cell cycle. Use the diagram to determine which each step of the cell cycle. A = InterphaseB = G1C = SD = G2E = ProphaseF = MetaphaseG = AnaphaseH = TelophaseI = MitosisJ = Cytokinesis Use the image to answer the questions below. This image is shuffled and the stages are NOT in order. A = ProphaseB = TelophaseC = MetaphaseD = InterphaseE = Anaphase Match the phase with the correct definition. prophase nucleus disappears; centrioles appear; DNA condenses metaphase sister chromatids (chromosomes) line up in middle anaphase sister chromatids (chromosomes) begin to separate telophase two nuclei form Match the stage with the correct definition. Interphase the "inbetween" period before division. G1 organelles are replicated, 1st major cell growth stage S DNA is replicated G2 Cell prepares to divide by growing and making proteins 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 If a cell has 24 chromosomes and does mitosis, how many chromosomes will each new daughter cell have? 12 24 48 Match the definition with the correct term. genetic information held together by a centromere chromosome Tightly coiled genetic information made up of two identical chromatids sister chromatids unwound DNA chromatin The cell cycle is the process by which cells reproduce to create two genetically identical daughter cells. Cell reproduction is mostly used for growth and repair in our body. The first major step of the cell cycle is interphase. During this phase the cell replicates its organelles, DNA, and grows in size in preparation for division. After interphase, the cell is prepared to start dividing the nucleus and genetic material in the second major step of the cell cycle we call mitosis. Once mitosis is complete and the genetic material has been divided evenly into two nuclei the process of cytokinesis begins. During cytokinesis the cytoplasm of the cell begins to pinch in causing the cell to separate into two genetically identical daughter cells.
