Step by step
Solved in 2 steps
- Explain the cell division limit and its fail-safe functionname the enzymes of matrix biosynthesis, which should correct violations of the DNA structure in the norm, indicate its localization, connection with the phases of the cell cycle, energy sourcesDescribe the function of these molecules that help control the cell cycle A.) M-phase promoting factor B.) Cyclin C.) Cyclin dependent kinase
- What is the significance of the cell cycle control system and checkpoints? Explain step by step in your own words. [please make it simple]Explain the roles of positive cell cycle regulators compared to the negative regulatorsDescribe the molecules that control the cell cycle through positive and negative regulation.
- If a drug interferes with the formation of microtubules , its effectiveness must be related to disruption of mitotic spindle formation suppression of cyclin production inhibition of DNA synthesis myosin denaturation and inhibition of cleavage formationWhat are the most important steps in cell-cycle regulation? Give some explanations and present some factors leading to uncontrolled cell cycle.Why is a rapidly growing tissue, such as the root tip of a plant, a good model for studying the effects of a drug on cell division?
- Give the possible results if cells won’t undergo cell division or if the cell cycle happens rapidly and becomes out of control.Which of the following is the primary method by which cyclin proteins are regulated to influence entry into the cell cycle or transition from one stage to the next? A. Transcriptional upregulation and translation followed by targeted ubiquitin-mediated degradation by a proteasome. B. Phosphorylation to regulate the activity of the kinase site. C. An activating phosphorylation and an inactivating phosphorylation. D. All of these are mechanisms that can be used to regulate cyclins.The cell cycle control system is a cycling set of molecules in the cell that triggers and coordinates key events in the cell cycle. This is all controlled by growth factors. a) Identify the major checkpoints in a cell and its function. b)Explain the role of the growth factor.
