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?
WHAT IF? What might be the resultif the cell ignored either checkpoint andprogressed through the cell cycle?
Cell Cyle and Checkpoints Story
Make a creative short story about the phases of cell cycle and its checkpoints. Highlight each function of the checkpoints and the characteristics of the cell during the different stages of the cycle.

- WHAT IF? As a cell begins the process of dividing, itschromosomes become shorter, thicker, and individuallyvisible in an LM (light micrograph). Explain what is happening at the molecular level.arrow_forwardObjective: To review the phases of mitosis with the understanding that in a real tissue or a non-synchronized cell culture, different mitotic phases and cells in interphase will be observed at a certain time. Interphase is the period between mitotic events; all other phases are part of mitosis and their individual probabilities add up to the total probability of seeing cells undergoing mitosis. Pay attention to the individual probabilities for cells in each phase of the cell cycle. Problem N° 10 For a certain type of animal tissue, the probability of a randomly selected cell being in a particular stage of the interphase/mitosis cycle is given by the following table: Stage Probability Interphase 0.5 Prophase 0.1 Metaphase 0.05 Anaphase 0.2 Telophase 0.15 Suppose you examine 100 cells at random from this tissue.
