- Examine the picture of an onion root tip with cells in various stages of the cell cycle. A student claims that interphase is the longest stage of the cell cycle. Another student claims that mitosis is the longest stage. Using evidence from the photo, determine which student is correct and why A)mitosis is the longest stage because anaphase requires more time to separate chromatids B) interphase is the longest stage because chromosomes are visible in the majority of the cells C) mitosis is the longest stage because the majority of the cells in the photo are replicating their dna D) interphase is the longest stage because the majority of the cells in the photo have uncondensed chromatin and are not dividingIf 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?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?
- Scientists are able to isolate cells in various phases of the cell cycle. During an experiment in which Dr. Patrick McGroyn is causing cultured tumor cells to go through mitotic cell division, he isolates a group of cells that contain one and a half times more DNA than cells isolated in the G1 phase have. What phase must these cells be in? How do you know?A scientist is analyzing the effects of a newly discovered cellular compound. She obtains two samples of diploid cells (2n), each with the same number of cells, and places sample 1 in a saline solution and sample 2 in a saline solution containing the newly discovered compound. She then incubates the cells for 24 hours. A bar graph of the results is shown below. Explain how the compound most likely affected the cell’s progression through the cell cycle, and predict the relative number of cells found in each sample when the results were observed. Support your claims with evidence from the experiment.1) Examine the picture of an onion root tip with cells in various stages of the cell cycle. A student claims that interphase is the longest stage of the cell cycle. Another student claims that mitosis is the longest stage. Using evidence from the photo, determine which student is correct and why. A) Mitosis is the longest stage because anaphase requires more time to separate chromatids. B) Interphase is the longest stage because chromosomes are visible in the majority of the cells. C) Mitosis is the longest stage because the majority of the cells in the photo are replicating their DNA. D) Interphase is the longest stage because the majority of the cells in the photo have uncondensed chromatin and are not dividing. Not Graded
- In class, we talked about flow cytometry which allows scientists to determine what stage of the cell cycle cells are in by measuring their DNA content. Draw what the graph would look like for the mutant below at a 0-time point when there are 1000 cells total, with 5000 cells in G1, 350 cells in M and G2, and 150 cells in S phase. And then a graph of 1 hour later when the cells should have competed for mitosis: → loss of function of cdc25What 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.Name the phases of the cell cycle. b) During which phases are the chromosomes and then the cytoplasm split, respectively? c) Describe one mechanism that is used to regulate the cell cycle.
- According to the figure, what environmental factor is affecting the cell and in which phase of the cell cycle is this occurring?4) Describe in detail how p53 and MDM2 regulate cell division in a normal, healthy cell. You should describe 1) how these proteins cooperate to allow a cell to go through the cell cycle, 2) how they cooperate to stop the cell cycle, and 3) how they allow the cell cycle to continue again after having stopped it initially. You may use point form if you want.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?
