- Why is cell furrowing important in cell division? If cytokinesis did not occur, what would be the end result?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?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?
- 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 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?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? Explain

Not GradedA biologist examines a series of cells and counts 160 cells in interphase, 20 cells in prophase, 6 cells in prometaphase, 2 cells in metaphase, 7cells in anaphase, and 5 cells in telophase. If the complete cell cycle requires 24 hours, what is the average duration of the M phase in these cells? Of metaphase?
- Put a checkmark next to any of the following scenarios that would make it MORE likely that a cell would divide when it is not supposed to, increasing the chance that it would become cancerous. CHOOSE ALL THAT APPLY. A) A tumor suppressor gene is over-expressed B) A cyclin gene is mutated so that it is expressed at all times during the cell cycle C) A cyclin-dependent kinase gene is mutated so that in the Cdk is no longer dependent on its cyclin D) A Cdk gene is mutated so that the Cdk protein is not made E) Mutation of an oncogene that causes it to no longer be expressed F) A proto-oncogene gene is expressed at higher than normal levels G) The p53 gene is mutated so that no p53 protein is madeDuring which stage of the cell cycle would a cell contain the least total amount of DNA?A biologist examines a series of cells and counts 160 cells in interphase, 20 cells in prophase, 6 cells in prometaphase, 2 cells in metaphase, 7 cells in anaphase, and 5 cells in telophase.
