What steps in the cell cycle represent irreversible commitments? a. The $\mathrm{S} / \mathrm{G}_{2}$ checkpoint b. The $G_{1} /$ S checkpoint c. Anaphase d. Both b and c are correct.
Added by Ryan W.
Step 1
During the G1 phase, the cell grows and prepares for DNA replication. At the G1/S checkpoint, the cell makes an irreversible commitment to enter the S phase and proceed with DNA synthesis. This checkpoint ensures that the cell has all the necessary resources and Show more…

Which of the following is NOT an example of how checkpoints internally regulate the cell cycle? a. At the G1 checkpoint, the cell may exit the cell cycle and enter nondividing. b. The M checkpoint is cleared if kinetochores are properly attached to their microtubules. c. PDGF can signal cells to grow and divide d. Passing the G2 checkpoint means the cell is cleared to enter the mitosis phase
Imaan A.
Which of the following does NOT correctly describe a cell cycle checkpoint? A. The spindle assembly checkpoint pathway prevents premature metaphase entry by sensing unattached kinetochores B. The growth checkpoint pathway ensures that cells acquire enough biomass to enter the cell cycle and produce two daughter cells C. The DNA damage checkpoint prevents cell cycle entry in the presence of DNA damage by activating kinases whose targets induce cell cycle arrest D. The spindle position checkpoint pathway ensures that each resultant cell receives a full genetic complement by sensing spindle pole movement along the cytokinesis axis

Describe the sequence of mitotic cell cycle for one pair of chromosome that is undergoing normal mitotic division. a. anaphase - metaphase - prophase - cytokinesis b. anaphase - prophase - metaphase - cytokinesis c. prophase - anaphase - metaphase - cytokinesis d. prophase - metaphase - anaphase - cytokinesis
