Textbook Question
Chapter 24, Problem 24.6PS
Cell Cycle Regulation. Recall that one approach to the study of cell cycle regulation has been to fuse cultured cells that are at different stages of the cell cycle and observe the effect of the fusion on the nuclei of the fused cells (heterokaryons). When cells in G1 are fused with cells in S, the nuclei from the G1 cells begin
- (a) The activation of DNA synthesis may result from the stimulatory activity of one or more cytoplasmic factors.
- (b) The transition from S to G2 may result from the presence of a cytoplasmic factor that inhibits DNA synthesis.
- (c) The transition from G2 to mitosis may result from the presence in the G2 cytoplasm of one or more factors that induce chromatin condensation.
- (d) G1 is not an obligatory phase of all cell cycles.
- (e) The transition from mitosis to G1 appears to result from the disappearance or inactivation of a cytoplasmic factor present during M phase.

- Dynamic instability causes microtubules either to grow or to shrink rapidly. Consider an individual microtubule that is in its shrinking phase. What would need to happen at the end of the microtubule in order for it to stop shrinking and to start growing again? Be specific! What would happen if only GDP, but no GTP, were present in the solution? What would happen if the solution contained an analog of GTP that cannot be hydrolyzed?arrow_forwardcells undergo programmed cell death. Write out the pathway(s), noting the changes (e.g., localization, phosphorylation, activation) When mammalian cells are irradiated, they stop dividing by arresting at cell cycle checkpoint. If the damage persists, the kinase (CdK), Cdk inhibitor, cytochrome c, DNA damage, mitochondria, p53, phosphorylation, transcription. each step.

At the indicated times the chromosomal DNA was extracted and analyzed by gel electrophoresis, which separates the DNA fragments based upon size differences. When cells undergo apoptosis their DNA is cut into fragments that are approximately multiples of 200 base pairs. This results in a characteristic “ladder" appearance when the fragments are separated by gel electrophoresis, as shown above. Based upon what you know about eukaryotic chromatin, explain why this pattern of DNA fragments is obtained. 6.arrow_forward

- True or Falso. Both p53 and kinesins can become phosphorylated. Select one: a. true b. falsearrow_forwardTrue or false. The cell walls of plants prevent the process of cytokinesis.arrow_forwardOh no! A mutation in the gene for G2 CDK has caused a problem with binding of the G2 cyclin. This prevents formation of the MPF. What would this mean for cell division and why? Select one: a. The MPF is needed for anchorage dependence. So without the MPF, the cell cannot anchor to a substrate. b. Without the MPF, gene expression for enzymes of DNA replication will be halted stopping S phase of interphase but not stopping cell division. c. Without the MPF, phosphates won't be added to the nuclear lamina so DNA will not be moved around the cell and cell division is effectively halted. d. Without the MPF, the APC will not add ubiquitin to the intermediate filaments of the nuclear lamina stopping cell division.arrow_forward
