  1. Cell Cycle Regulation Learning Activities To be completed in your notebook

  2. State the Importance of Each Checkpoint in a Summary • G1 checkpoint • Cell size is adequate • Nutrients are sufficient • Social signals are present (signalling molecules from other cells) • DNA is undamaged • Metaphase checkpoint • All chromosomes are attached to spindle apparatus • G2 checkpoint • Chromosomes have replicated successfully • DNA is undamaged • Activated MPF is present

  3. Describe how the cell cycle is regulated http://highered.mcgraw-hill.com/olcweb/cgi/pluginpop.cgi?it=swf::535::535::/sites/dl/free/0072437316/120082/bio34a.swf::Control%20of%20the%20Cell%20Cycle • What is MPF? What does it do? • State the purpose of a threshold of MPF. Threshold is the amount needed for the cell cycle to progress • State the purpose of Cyclin • State the purpose of Cdk • Describe the function of at least one enzyme and name its substrate.
