Researchers studying cell cycle regulation in budding yeast have observed that a mutation in the CDC15 gene causes cell cycle arrest in telophase when the yeast cells are incubated at an elevated temperature. Which of the following statements best predicts the effect of the cell cycle arrest on proliferating yeast cells? A The yeast cells will transition out of G_(0) but will fail to complete the G_(1) phase. B The yeast cells will initiate mitosis but will fail to complete the G_(2) phase. C The yeast cells will replicate their chromosomes but will fail to complete cytokinesis. D The yeast cells will replicate their organelles but will fail to complete the S phase.

The correct answer is C. The yeast cells will replicate their chromosomes but will fail to complete cytokinesis.<br /><br />Explanation:<br />- The CDC15 gene is involved in the regulation of the cell cycle, specifically in the transition from telophase to cytokinesis.<br />- A mutation in the CDC15 gene causes cell cycle arrest in telophase, which means the yeast cells will replicate their chromosomes but will fail cytokinesis.<br />- Cytokinesis is the process of cell division that divides the cytoplasm into two daughter cells. If cytokinesis is not completed, the yeast cells will be arrested in telophase, with replicated
