Cell Cycle Review 1 Which of the following observations can be made when an animal cell is in metaphase? A B C D 2 Which stage of the cell cycle does the cell spend most of its time in? A B C D E 3 prophase anaphase telophase metaphase Cytokinesis is the division of A B C D 6 G1 phase G2 phase S phase M phase In what phase of mitosis do the two "sister chromatids" of a chromosome separate from each other and begin moving towards opposite ends of the cell? A B C D 5 prophase anaphase telophase interphase metaphase In what phase of the cell cycle does the duplication of chromosomes occur? A B C D 4 The spindle fibers are not present. The chromosomes are not condensed. The cell membrane is pinching off to form two cells. The chromosomes are aligned along the center of the cell. the spindle. the nucleus. the cytoplasm. a chromosome. The stage of mitosis in which the nuclear membrane begins to break down and eventually disappear is: A B C D prophase anaphase telophase metaphase 12/2/2004 2:56:00 PM Page 1 Cell Cycle Review 7 A cell has 24 chromosomes during the "G1" phase of interphase. After this cell goes through the process of mitosis, there are two daughter cells. Each of these daughter cells has A B C D 8 The events that happen during telophase can be thought of as the reverse of the events that happen in A B C D 9 prophase anaphase telophase interphase metaphase Which of the following does cytokinesis normally accomplish? A B C D 12 Production of a cancer cell Production of two identical daughter cells Production of two nuclei with identical sets of chromosomes Precise division of the cytoplasm and its distribution to two daughter cells In what part of the cell cycle does DNA replication occur? A B C D E 11 prophase. anaphase. telophase. metaphase. Which of the following does mitosis normally accomplish? A B C D 10 6 chromosomes. 12 chromosomes. 24 chromosomes. 48 chromosomes. Production of a cancer cell Production of two identical daughter cells Production of two nuclei with identical sets of chromosomes Division of the cytoplasm and its distribution to two daughter cells The stage of mitosis in which the nuclear membranes start to rematerialize and the chromosomes go back to their original state is called _____________.

A B C D 14 Cell division is a crucial process for which of the following characteristics of life? A B C D 15 The spindle apparatus is present. The chromosomes are condensed and visible. The cell membrane is pinching off to form two cells. The chromosomes are aligned along the center of the cell. growth reproduction organization both A and B When during the cell cycle are chromosomes visible under a microscope? A B C D only during interphase only during G1 of interphase only when they are being replicated only during the mitotic phase (cell division) 12/2/2004 2:56:00 PM Page 3 Cell Cycle Review Page 4 Answer Key : Cell Cycle Review Question: 1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 12/2/2004 2:56:00 PM 12/2/2004 2:56:00 PM Answer D D C B C A C A C D D C C D D
