  1. A bacterial cell divides into two new cells by an asexual process called __________. A) duplication. B) meiosis. C) binary fission. D) mitosis.

  2. Mitosis is completed with the production of two genetically identical cells which are both: A) diploid with unpaired chromosomes. B) diploid with paired chromosomes. C) haploid with unpaired chromosomes. D) haploid with paired chromosomes. E) sperm or egg cells.

  3. Sister chromatids are A) replicated chromosomes held together by a common centromere. B) specialized gamete-forming cells. C) non-functional chromosomes. D) homologous pairs of chromosomes. E) different in their genetic content.

  4. Chromosome replication occurs during A) G1 phase B) G0 phase C) Prophase D) S phase E) none of the above are correct

  5. The mitotic spindle is primarily composed of ________ which are sent out to attach to and separate chromosomes. A) actin fibers B) intermediate filaments C) microtubules D) keratin E) motor proteins

  6. The protein complex on each centromere where the spindle fibers attach is called the A) Chromosome B) Basal body C) Kinetochore D) Centriole E) Metaphase plate

  7. Sister chromatids are pulled apart and move to opposite ends of the cell A. metaphase B. prophase C. telophase D. anaphase E. cytokinesis

  8. Chromosomes line up along the equator of cell A. metaphase B. prophase C. telophase D. anaphase E. cytokinesis

  9. Cells are divided into two approximately equal halves, each getting about the same amount of cytoplasm A. metaphase B. prophase C. telophase D. anaphase E. cytokinesis

  10. Duplicated chromosomes condense; Spindle microtubules form; Chromosomes attach to spindle A. metaphase B. prophase C. telophase D. anaphase E. cytokinesis

  11. Chromosomes uncoil into chromatin; Nuclear envelope reforms A. metaphase B. prophase C. telophase D. anaphase E. cytokinesis

  12. Progression through the check points of the cell cycle is regulated by fluctuating concentrations of ______. A) kinetochore B) cyclin C) ATP D) cyclin-dependent kinases

  13. Which one of the following is true about cancer cells? A) Mitosis is strictly regulated and is regulated by contact inhibition. B) Cancer cells form tumors only when strongly anchored to surrounding tissues. C) Cancer cells display uncontrolled cell division typically caused by insertion or activation of oncogenes. D) Tumors formed by cancer cells become encapsulated and always remain isolated in one location.
