The Cell Cycle, Mitosis, and Meiosis
Review
At the end of this unit, students should be able to answer the following
questions:
 Describe binary fission.
 What is mitosis?
 Identify the phases of the eukaryotic cell cycle.
 What happens during interphase?
 Define cancer.
 How might the relationship between cancer and the cell cycle
be used in the search for causes of cancer?
 Cells go through a series of events that include growth, DNA
synthesis, and cell division. Why are these events best
represented by a cycle diagram?
 Contrast cell division in prokaryotes and eukaryotes. Why are
the two types of cell division different?
 Explain how the cell cycle is regulated.
 Why is DNA replication essential to the cell cycle?
 What are chromosomes? When do they form?
 Identify the chromatids and the centromere of a chromosome.
 List the phases of mitosis.
 What happens during prophase of mitosis?
 During which phase of mitosis do sister chromatids separate?
 Describe what happens during cytokinesis in animal cells.
 If a cell skipped metaphase during mitosis, how might this
affect the two daughter cells?
 Explain how chromosomes are related to chromatin. Why are
chromosomes important for mitosis?
 Explain the significance of the spindle in mitosis.
 What are three types of asexual reproduction?
 Define gamete and zygote. What number of chromosomes does
each have?
 What happens during fertilization?
 Outline the phases of meiosis.
 What is a life cycle?
 What is gametogenesis, and when does it occur?
 Create a diagram to show how crossing-over occurs and how it
creates new gene combinations on each chromosome.
 An adult organism produces gametes that quickly go through
fertilization and form diploid zygotes. The zygotes mature into
adults, which live for many years. Eventually the adults
produce gametes and the cycle repeats. What type of life cycle
does this organism have? Explain your answer.
 Compare and contrast asexual and sexual reproduction.
 Explain why sexual reproduction results in genetically unique
offspring.
 Explain how meiosis I differs from mitosis.
