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
What physiological differences between S. pombe and S. cerevisiae make them useful yet complementary tools for studying the molecular mechanisms involved in cell cycle regulation and control?
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.
The frog egg system was critical for developing genetic screens for identifying genes important for cell cycle regulation.
Cytoplasm extract from plant cells was used to identify factors important for cell cycle progression.
Temperature-sensitive mutants are critical for identifying genes essential for cell division.

- Analysis of Cell-Cycle Mutants in Yeast?arrow_forwardThe cell-cycle control system is based on a connected series of biochemical switches which possess many important features that increase the accuracy and reliability of cell-cycle progression. Discussarrow_forwardLet'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?

- Need help fast What molecular mechanisms operate to ensure that once the decision to advance through the restriction point has been made, this leads to an essentially irreversible commitment to complete the remaining phases of the cell cycle through M phase?arrow_forwardTo 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_forwardWhich of the following is TRUE regarding the Steward's (1950s) carrot experiment and Gurdon et al. (1975) nuclear transplantation experiment? O While both studies supported the differential expression of genetic material hypothesis, Gurdon et al. (1975) highlighted the role of differentiation on the genetic potential of a nucleus. O While both studies supported the "progressive loss of genetic material hypothesis, Gurdon et al. (1975) highlighted the role of differentiation on the genetic potential of a nucleus. O While Gurdon et. al's (1975) study clearly supported the differential expression" hypothesis, Steward's (1950s) carrots supported the progressive loss" hypothesis, highlighting the role of differentiation on nuclear potential.
