Textbook Question
Chapter 9, Problem 1AC
Most nerve cells in the adult human central nervous system, as well as heart muscle cells, do not divide. In contrast, cells lining the inside of the small intestine divide frequently. Discuss this difference in terms of why damage to the nervous system and heart muscle cells (for example, that caused by a stroke or heart attack) is so dangerous. What do you think might happen to tissues such as the intestinal lining if a disorder blocked mitotic cell division in all cells of the body?

One important biological effect of a large dose of ionizing radiation (like X-rays) is to halt cell division.
How does this occur? To answer this question, state the name and role of 2 specific and important proteins involved in the process.
What happens if a cell has a mutation that prevents it from halting cell division after be irradiated? Be specific and detailed.
An adult human who has reached maturity will die within a few days of receiving a radiation dose large enough to stop cell division. What does that tell you about cell division? In addition, name 2 different/unique cell types that would be primarily affected.
In the mitosis experiment, in what stage were most of the onion root tip cells in? Based on what you know about cell cycle division, what does this imply about the life span of a cell? Were there any stages of the cell cycle that you did not observe? How can you explain this using evidence from the cell cycle?
In the tracking chromosomal DNA movement through mitosis experiment, how many chromosomes did each of your daughter cells contain? Why is it important for each daughter cell to contain information identical to the parent cell? How often do human skin cells divide? Why might that be? Compare this rate to how frequently human neurons divide. What do you notice?

- 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.arrow_forwardScientists 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?arrow_forwardSome 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?arrow_forward
- What is the name of the cytoplasm division in the end of mitosis? What are the differences in this process between animal and plant cells?arrow_forwardA scientist studying a group of somatic cells notices that when the cell cycle is complete, half of the daughter cells have no chromosomes and the other half have 92 chromosomes. In what phase of mitosis did an error most likely occur? Explain.arrow_forward• Describe one event that occurs in prometaphase of mitosis in eukaryotic cells. • Describe one event that occurs in telophase of mitosis in eukaryotic cells.arrow_forward
- Which stage of the cell cycle is the longest? Why are onion root tips a good choice for viewing cells in different stages of the cell cycle? Are there any mammalian cells that would be a good source for dividing cells? What types of cells would most like NOT have cells undergoing division?arrow_forwardExplain the difference between asymmetric and symmetric cell division. When the pool of stem cells for a particular tissue needs to expand, which of these two cell division mechanisms is utilized?arrow_forwardwhich stage of the cell cycle do cells spend most of their time in? Explain why you think this is. Explain why mitosis is important to both unicellular and multicellular organisms. discuss how a carcinogen causes mutations that could cause the body to lose control over mitotic events and apoptosis (cell death). What can we do to protect ourselves from the harmful effects of carcinogens?arrow_forward
- In general, are somatic cells genetically identical? Why or why not? Group of answer choices 1. yes - they come from meiosis 2. no - they come from mitosis 3. yes - they come from mitosis 4. no - they come from meiosisarrow_forwardWhich tissues in the human body would you expect to have a low mitotic index, and which would you expect to have a high mitotic index? Explain your reasoningarrow_forwardHuman cells divide every day for normal growth, replacement of cells, and tissue repair. The dividing cells proceed through the three phases of the cell cycle as shown in the figure. When a person experiences a cut, damaged skin cells secrete a protein called epidermal growth factor (EGF). Epidermal (skin) cells in the vicinity of the injury possess proteins in their cell membranes called epidermal growth factor receptors (EGFR) Cancer can result from disruptions in cell cycle control. Mutations that increase the production of EGFR have been associated with skin cancer of the head and neck. Describe how a mutation outside of the coding region of a gene that encodes EGFR could lead to the overproduction of EGFR protein in a skin cell.arrow_forward
