- Some cells in organisms can divide on a daily basis while others do not divide as often. Which phase of the mitosis do you think would vary the most due to different rates of cell division and why?If you were to look at a sample of “normal” cells, what phase of the cell cycle do you think most of the cells would be in? If you were to look at a sample of cancer cells, what phase of the cell cycle do you think most of the cells would be in?The cell cycle is highly regulated and involves many steps to ensure that a cell is ready to divide. For this reason, cells cycle between interphase and mitosis. Which of the following describes the consequence of a severe disruption of interphase in cells in healthy tissue? Disruption of interphase will have no effect on mitosis because they are two completely independent processes. Disruption of interphase will lead to a faster and more efficient mitotic cycle, which will result in increased cell division and tissue growth. Disruption of interphase will trigger the cell to switch to a mitotic phase and repeatedly divide, which will result in the massive proliferation of the cells and heightened tissue growth. Disruption of interphase will result in the cell being unable to synthesize proteins and organelles required to divide, which will result in the cell not passing key checkpoints and ceasing to divide.
- 1) what is meant by “there is no such thing as a typical cell?” 2) which part of the cell cycle does the cell spend the least amount of time in? Why do u think that is? 3) why would a cell ever want to destroy itself? 4) how long does a cell live before it undergoes mitosis? 5) if cells can constantly replace themselves, why is a heart attack (which kills cardiac muscle cells) so devastating? 6) what type of cells never undergo mitosis? 7) what makes stem cells particularly interesting to researchers? 8) how might stem cells be used to repair brain or heart damage, even though these cells do not undergo mitosis? 9) why do you think beauty experts would also be interested in stem cells? 10) what is the connection between cancer and mitosis? 11) why is it so difficult for your body to battle cancer? 12) why does you hair fall out of the chemotherapy?Why is the interphase considered the longest phase in cell division?How long does it take for a cell to take one complete cycle? The answer varies on the type of cell and the species. For instance, a liver cell completes its cell cycle for over 22 hours (Becker and Lane 1965) while other somatic cell lasts to about 18 hours. Can you cite other types of cells that undergo cell cycle and the time it takes to complete the cycle? List five below.
- If a mad scientist hands you a cell culture with 100 cells that just entered g1. He needs to extract the MOST possible DNA from 100 cells. On top of that, he requires that the DNA cannot be condensed. To accomplish this goal he gives you a set of chemicals that will stop a cell in any part of the cell cycle you want. What part of the cell cycle would you stop the cell at, that matches those requirements?The process of cellular reproduction or divisions is a heavily regulated process for a number of different reasons. In the case of the eukaryotic cell there are a number of different checkpoints that a cell must pass before it can continue on. Please explain what those checkpoints are looking for and where those checkpoints are in the cell cycle. If a cell doesn’t pass any of these checkpoints what happens to those cells?Which of the following statements is correct about the cell cycle? In actively dividing cells, the S and G2 phases are collectively known as interphase. O A. The cell cycle is a sequence of replication and division that produces new cells. O B. When the S phase of the cell cycle is finished, a cell actually has twice as many chromatids as the number of chromosomes in the Gl phase. OC. The phases of the cell cycle are G1, S, and M. OD.
- What is the major difference between M phase and interphase of the cell cycle? We can see activity within the cell only during M phase. Interphase is when the cell divides, whereas M phase is where it is mute. We can see activity within the cell only during interphase. M phase involves color changes, which is why there are chromosomes.Why do you think the rate of cell division is different for different tissues? Where in the body would you expect to find cells that have a rapid rate of division? Where might you find cells that have a slow rate of division? ExplainA cell cycle is a series of events that takes place in a cell as it grows and divides. A cell spends most of its time in what is called interphase, and during this time, it grows, replicates its chromosomes, and prepares for cell division. Can you explain the control of the cell cycle in depth.
