Let's say that an experiment had no disruption to kinetochores and you are able to inactivate the CDC 14 phosphatase, which acts to remove phosphate groups from substrates that were previously phosphorylated by active MPF. What effect, if any, would this have on (i) the duration (length) of the mitotic phase, (ii) the timing of cyclin B’s appearance or disappearance, and (iii) the period of time for which MPF is active? Briefly explain your reasoning
Let's say that an experiment resulted in the production of several unattached kinetochores. What effect, if any, would this have on (i) the duration (length) of the mitotic phase, (ii) the timing of cyclin B’s appearance or disappearance, and (iii) the period of time for which MPF is active? Briefly explain your reasoning.

- To identify genes controlling the cell cycle in budding yeast, a genetic screen was carried out. In this screen, haploid yeast cells were exposed to a DNA damaging agent to introduce random mutations in the genome. By culturing cells at an elevated temperature (e.g. 37 degrees), where many mutated genes lose their function, scientists identified yeast mutants that showed growth defects and arrest at specific stages of the cell cycle (e.g. in mitosis with large buds). In this screen, mutants of the cyclin-dependent kinase were identified, but not mutants of cyclins. Explain the reason for this outcome.arrow_forward6 1117121 There are several main model systems through which the first set of major breakthroughs in the understanding of cell cycle control was made. Indicate whether each of the following statements is likely to be true or false for this initial phase of discovery. [ Select] identifying genes important for cell cycle regulation.

- If chemical signals in the cytoplasm control the progression of a cell to the M phase of the cell cycle, then fusion of a cell in G1 with a cell in early M phase would most likely result in the (A) replication of chromosomes only in the G1 cell (B) exiting of both cells from the cell cycle and into the G0 phase (C) condensation of chromatin in preparation of nuclear division in both cells (D) transfer of organelles from the G1 cell to the cell in the M phase Please select the correct option. For the incorrect options, please explain why each one is incorrect.
