6、The drug Cytochalasin D inhibits actin formation in a cell while preserving the structure of the rest of the cytoskeleton. Which of the following processes of the cell cycle would be disrupted by exposure to Cytochalasin D?

7、The following two questions refer to one experiment. Two researchers performed an experiment based on their hypothesis that the progression of the cell cycle is controlled by molecules from within the cytoplasm. To investigate this hypothesis, they chose cultured mammalian cells in different phases of the cell cycle and induced them to fuse. Below is a sketch of two of the cells at the beginning of the experiment.

Assuming that the researchers’ hypothesis is correct, choose the image that correctly predicts the result of the experiment after fusion.

8、Refer to the same two cells sketched in Question 7. If the progression of the phases of the cell cycle was not triggered by molecules from the cytosol, but instead each cell moved into the next phase automatically after completion of its current phase, which of the following correctly predicts what would happen to the original two fused cells?

9、Which of the following is a characteristic of mitosis but is not a characteristic of meiosis?

10、During which phase of the cell cycle does crossing over occur?
