The Cell Cycle DNA Structure, Replication, and Mitosis (continued) Review Questions: 1. Describe the molecular structure of DNA. Be sure to include the base paring rules. 2. DNA replication is often described as semiconservative. What does this mean? 3. What are sister chromatid? What phase of the cell cycle do they appear? 4. Name at least one event involving the chromosomes that occurs in the following stages of the cell cycle and mitosis. A. Interphase B. Mitosis a. Prophase: b. Metaphase: c. Anaphase: d. Telophase: 5. Cells resulting from mitotic division are often described as being clones of the mother cell. Why is this true? 6. How is mitosis different from cytokinesis? 7.

(Hint: think about the topic of this lab) 9. Folic acid (one of the B vitamins) is necessary for the normal incorporation of thymine (one of the four nitrogen bases) into DNA. Why are neural tube and brain defects often seen in the babies of women who do not get enough folic acid in their diets during pregnancy? (Hint: Think about the events of the cell cycle and the rapid growth and development occurring in embryonic development.) 10. The following diagram shows animal cells in different phases of the cell cycle and mitosis. Label each cell with the appropriate phase. (Hint: A nucleus with small, dashed-lines indicate that the individual chromosomes are not visible.) 9
