Unformatted text preview: Exam 4 Use ScanTron MULTIPLE CHOICE. Choose the one alternative that best completes the statement or answers the question. 1) The centromere is a region in which A) metaphase chromosomes become aligned at the metaphase plate. B) new spindle microtubules form at either end. C) the nucleus is located prior to mitosis. D) chromatids remain attached to one another until anaphase. E) chromosomes are grouped during telophase. 2) If there are 20 chromatids in a cell, how many centromeres are there? A) 40 B) 80 C) 20 D) 30 E) 10 H T h e d a u g h t e r c ells have the same numbe r of chrom osome s and twice the amoun t of DNA. T h e d a u g h t e r c ells have the same numbe r of chrom osome s and the same amoun t of DNA. T h e d a u g h t e r cells have half the amoun t of cytopla sm and half the amoun t of DNA. W pro metaphase prophase C) anaphase D) telophase E) metaphase 5) Which term describes centromeres uncoupling, sister chromatids separating, and the two new chromosomes moving to opposite poles of the cell? A) metaphase B) prophase C) telophase D) anaphase E) prometaphase 6) Where do the microtubules of the spindle originate during mitosis in both plant and animal cells? A) centromere B) chromatid C) centriole D) kinetochore E) centrosome 7) Regarding mitosis and cytokinesis, one difference between higher plants and animals is that in plants A) sister chromatids are identical, but they differ from one another in animals. B) a cell plate begins to form at telophase, whereas in animals a cleavage furrow is initiated at that stage. C) spindle poles contain centrioles, whereas spindle poles in animals do not. D) chromosomes become attached to the spindle at prophase, whereas in animals chromosomes do not become attached until anaphase. E) the spindles contain microfibrils in addition to microtubules, whereas animal spindles do not contain microfibrils. 8) Which of the following are primarily responsible for cytokinesis in plant cells? A) actin and myosin B) centrioles and basal bodies C) Golgi- derived vesicles D) kinetochores E) cyclin- dependent kinases 9) During which phases of mitosis are chromosomes composed of two chromatids? A) from G 1 of interphase through metaphase B) from G 2 of interphase through metaphase C) from interphase through anaphase D) from metaphase through telophase E) from anaphase through telophase Use the following to answer the questions below....
