Step by step
Solved in 2 steps
- Prophase Metaphase Anaphase Telophase1. What are the four distinct phases of the cell cycle? What are the specific events that happen during each phase? 2. What are ensured by G, and G, as well as metaphase checkpoints? 3. What happens during the G, phase?12) when cells are placed in culture there is a lag period of time before an increase in number can be seen. During this period the cells are reentering the cell cycle early in G1 to resume the cell division cycle true or false
- A cell can normally halt its progression through the cell cycle at different checkpoints. Which of the following best predicts a reason for a cell to halt its progression through the cell cycle between the G1 and the S phases? A B incorrect attachment of spindle fibers to sister chromatids с insufficient accumulation of nucleotides D mitosis-facilitating enzymes have not been synthesized errors in DNA replication during G13) Draw a diagram of the cell cycle (G1, S..) and indicate places where errors in cell division might lead to cancer.Which of the following is least likely to result in the formation of a cancerous cell? A Dysfunction results in the permanent activation of a cell division pathway in the absence of the appropriate ligand. B с D Separation of chromatids during mitosis occurs without all centromeres being attached to spindle fibers from both poles. A dysfunction in a cell cycle checkpoint prevents a cell from entering the S phase. A dysfunction causes the inability to produce cancer-suppressing proteins.

Apoptosis 12. Check Points feedbackDuring the cell cycle there are three checkpoints. Match each description with the correct checkpoint. Requires growth signals and checks there are no mutation in the DNA Checks that DNA is properly replicated and that all the organelles and proteins needed for division are present Ensures that all the chromosomes are lined up and accounted for A. G1/S B. S/G2 C. G2/M D. Metaphase/Anaphase E. Anaphase/Telophase1. Damage to genomic DNA could result in each of the following except for? Inactivation of s cdk; activation of a checkpoint to halt cell cycle progression; activation of a protease that degrades cohesion; inactivated of m cdk 2.

During which stage of the cell cycle does chromosomes condensation occur? Metaphase; s phase; anaphase; prophase 4. What are the three locations of the calcium pumps that helps a cell to maintain a very low concentration of free calcium in the cytoplasm at the resting state?
- 1 Given the events of the cell cycle shown above, where would you predict there might be checkpoints where internal regulatory cyclins "look at" the cycle to see if the cell cycle should continue? Explain your reasoning. 2. Compare & contrast the cell during the G phase of interphase with the 2 daughter cells. (You may use a Venn diagram.) 3. Research which areas of the human body have very active mitotic activity, and write a short essay about your findings. Include information about why these areas are this way. Directions: Use the pictures to help with the 3 questions, I would really appreciate it. If you could explain how you got your answers separately that would be helpful but not necessary. Thank you so much.1. What structure on the chromosomes do the mictrotubule in the mitosis spindle attach to and drive the separation of the sister cell?
