1 ell ivision Review Game Page 1 1 "Mitosis" is the biological name for the process of cell division. True False 2 In what phase of mitosis does the spindle begin to form? prophase anaphase telophase 3 Which of the following observations can be made when an animal cell is in? E The chromosomes are condensed and visible. The chromosomes are aligned along the center of the cell. The cell membrane is pinching off to form two daughter cells. ll of the above oth and 4 Which of the following does mitosis normally accomplish? Production of two identical daughter cells Production of two nuclei with identical sets of chromosomes Production of two nuclei with different sets of chromosomes Precise division of the cytoplasm and its distribution to two daughter cells 5 uring which phase of mitosis do the "sister chromatids" become "daughter chromosomes?" anaphase prophase telophase 6 What part of the cell cycle can be thought of as the "lifetime of the cell?" interphase cytokinesis cell division 7 ccording to the textbook, the cell cycle includes 4 major phases. Which of the following lists them in the correct order? G1, S, G2, M G1, G2, S, M G1, S, M, G2 G1, M, G2, S 2/22/2010 7:45:28 M

2 ell ivision Review Game Page 2 8 Which of the following events takes place during the "G1" phase of the cell cycle? the cell divides the cell increases in size the chromosomes condense 9 uring the "S" phase of the cell cycle, the genetic material of a cell is copied through a process called N analysis. N creation. N replication. N reproduction. 10 What would be the most likely result of cell division if cytokinesis came before mitosis? oth daughter cells would die immediately. oth daughter cells would survive indefinitely. One daughter cell would have two nuclei and the other would have no nucleus. Four daughter cells would be produced, each with half the number of chromosomes as the parent cell. 11 Which of the following statements correctly describes one of the differences between mitosis and meiosis? mitosis produces two daughter cells, meiosis produces four. mitosis involves one round of cell division, meiosis involves two. mitosis produces genetically identical daughter cells, meiosis produces genetically different daughter cells. 12 In class, we discussed an analogy that compared and. sister chromatids; pieces of candy proto-oncogenes; the brakes of a car haploid daughter cells; conjoined twins homologous chromosomes; pairs of shoes 13 Meiosis is important because it allows populations the potential to adapt to changing environmental conditions. it ensures genetic variation in a population of sexually reproducing organisms. it halves the number of chromosomes in sex cells prior to sexual reproduction. 2/22/2010 7:45:28 M

Homologous chromosomes are exactly the same, sister chromatids are similar but not identical. Sister chromatids are exactly the same, homologous chromosomes are similar but not identical. Homologous chromosomes are inherited from the same parent, sister chromatids come from different parents. none of the above 17 ancer results from in the that control. problems; genes; meiosis mutations; genes; the cell cycle malfunctions; spindle fibers; mitosis duplications; chromosomes; cell division 18 When haploid cells combine during fertilization, they produce a diploid cell that is called a(n) egg. zygote. embryo. sperm cell. 19 In regular cell division, cytokinesis divides the cytoplasm of a cell producing two identical parent cells. two identical daughter cells. two genetically identical daughter cells. two genetically different daughter cells. 2/22/2010 7:45:28 M

Each of these daughter cells has 6 chromosomes. 12 chromosomes. 24 chromosomes. 48 chromosomes. 21 ccording to the textbook, the cell cycle includes 4 major phases.
