Please match the event to the correct subphase of interphase. You may use each subphase more than once. A cell may exit the cell cycle and become nondividing. DNA is replicated. Centrioles complete division. Enzymes and organelles double in number. Structures directly involved in cell division are synthesized. 1. G1 2. S 3. G2 Please match the numbered cells in this image to the correct stage of mitosis. Telophase Prophase Anaphase Metaphase 1. 1 2. 2 3. 3 4. 4

1- What is the best description of the major outcome of the cell cycle? - 2 daughter cell - a larger cell - several smaller cells - a round cell 2- What is the best description of the G0 phase? - the cell is dead - the cell will never undergo cell division - the cell is growing - the cell is not actively dividing but still metabolically active 3- What is the best description of the cell when in the S phase - the cell is resting - the cell is building protein, organelles, cytosol, etc - the cell is duplicating it's DNA - the cell is dividing 4- As the cell is surveying whether or not to pursue cell division, what is it checking for? choose all that apply. - if there is enough energy sources - if DNA was correctly duplicated - if it is being signaled from outside the cell to duplicate 5- which of the following represents the most complete and correct order of interphase? select one - G1-> S-> G2 - G2-> S-> G1 - G1-> S-> G2-> M - G2-> S-> G1-> M

QUESTION 1 During which of the following phases of the cell cycle does the cell have the LEAST amount of DNA? G1. G2. Metaphase. S. Prophase. QUESTION 2 In what phase of mitosis do chromosomes line up along the equator of the cell? Prophase. Telophase. Anaphase. Cytokinesis. Metaphase. QUESTION 3 A cell type that conducts meiosis and gives rise to gametes in humans is known as? Lymphoid cells. Somatic cells. Stem Cells. Schwann cells. Germ cells. QUESTION 4 Which of the following does NOT occur during M (mitosis) phase of the cell cycle? Chromosomes condense. DNA replication. Separation of sister chromatids. Nuclear envelope fragments (degrades). Centrosome formation. QUESTION 5 The interphase of the cell cycle does NOT include which of the following? M. G2. G0. S. G1. QUESTION 6 Cell division is NOT important for? Tissue growth. Reproduction. Fat storage. Tissue repair. It is not important for any of the above. QUESTION 7 Which processes occur when bacterial cells divide? Replication of DNA. Segregation/separation of replicated DNA. Cytokinesis (equal separation of cytosol). All of the above. QUESTION 8 Which of the following statements is FALSE for prokaryotes? Prokaryotic cell division is much faster than in eukaryotic cells. Prokaryotes usually have one closed, circular DNA chromosome. Prokaryotic cell division is subdivided into G1, S, G2, and M phases. Cell division in bacteria is referred to as binary fission. The prokaryotic genome has an "ori" site at which DNA replication begins. QUESTION 9 Which of the following is mismatched? S phase = period of cell cycle in which DNA is replicated. cytokinesis = division of cytoplasm. G2 phase = period of the cell cycle after DNA replication but before M phase. G1 phase = period of the cell cycle before initiation of DNA replication. M phase = division/separation of genetic material. QUESTION 10 A cell that cannot proceed past the G1/S phase checkpoint and is blocked from undergoing division is known as being in? Apoptosis. Mitosis. G2. G0. Meiosis.
