21. What is the sequence of events in a typical eukaryotic cell cycle?
22. The portion of the cell cycle when the cell is growing and does not contain a replicated
genome is referred to as:
23. The stage of the cell cycle during which the cytoplasm divides to form two cells is
called:
24. This stage of the cell cycle is characterized by growth and it contains a checkpoint to
verify that all of the DNA has been replicated prior to mitosis.

28. Embryonic cell cycles allow the rapid division of cells in the early embryo. These mitotic
cell cycles are much shorter in length than the mitotic cell cycles of cells in a mature
organism. In the embryonic cell cycles, mitosis takes approximately the same amount of time
as it does in the cell cycles of mature cells. What do you think is a result of the embryonic
cycle?

34. Consider the cell cycle of a human cell. During G2, what is the state of the homologous
chromosomes?
35. This is the stage of mitosis characterized by the alignment of the chromosomes in a ring
along the inner circumference of the cell:
Chapter 10 – How Cells Divide
36. The stage of mitosis characterized by the physical separation of sister chromatids is
called:
37. This stage of mitosis is characterized by the disassembly of spindle apparatus, the
reestablishment of the nuclear membrane, and the decondensation of the chromosomes:
38. During this stage of mitosis, the nuclear envelope begins to break down and the spindle
begins to form.

39. In prophase, ribosomal RNA synthesis stops when the chromosomes condense, and as a
result:
40. During this stage of mitosis, the chromosomes become attached to the spindle at their
kinetochores.
41. What happens during Anaphase B?

42. You are conducting a genetic screen using Caenorhabditis elegans embryos to isolate
mutations affecting anaphase (A). Therefore, you need to look for embryos in which
43. What stage of mitosis is essentially the reverse of prophase?
44. The drug Taxol, or Paclitaxel, is used to treat patients with a variety of cancers, including
breast, lung and ovarian cancers. The drug works by stabilizing microtubules, and preventing
their disassembly. The goal of the drug is to prevent dividing cells from being able to
complete mitosis. As a result, cancerous cells can no longer divide. In a cell treated with
Taxol, at what stage of mitosis will the cells arrest?
