Chapter 10, Problem 2ITD
Summary Introduction
To review:
Whether the radium exposure was permanent.
Introduction:
Mitosis is a part of the cell cycle or the division of a cell in which replicated chromosomes are separated into two new nuclei. The number of genetically identical cells to be maintained by cell division during mitosis, as one cell divides to form two identical cells. The major function of mitosis is cell growth and replacement of worn out cells.

Students have asked these similar questions
A group of cells is assayed for DNA content immediately following mitosis and is found to have an
average of 20 picograms of DNA per nucleus. Approximately how many picograms of DNA would
be found in a nucleus at prophase of mitosis?
Which is true for cancer cells:
1) Cell death occurs after a determined number of cell divisions
2) Contact with other cells reduces chance of cell division
3) Cell division occurs in the presence of stop signals.
3) Examine the graph showing the relative percentage normal and cancer cells spend in various stages of the cell cycle. Based on the information in the graphs, infer how cancer cells differ from typical, noncancerous cells. Select ALL that apply.
A) Cancer cells do not replicate their DNA.
B) Cancer cells replicate their DNA too quickly.
C) Cancer cells do not go through interphase during their cell cycle.
D) Cancer cells spend more time dividing compared to typical cells.
E) Cancer cells do not always grow to the same size as typical cells.

- List at least five (5) significance of mitosis.arrow_forwardYou have been asked to do a strucutural study to understand how increasing cell surface area affects cell size, cell shape and functions. What cell type would help you most efficiently observe the effects of increasing surface area? Choices: A. Monocytes from the blood serum. Monocytes are largely roughly spherical cells. B. Red Blood cells from the bone marrow. The shape of Red blood cells is a biconcave disk and looks like a donut. C. Stem cells from skin. In this case assume a skin stem cell is flat and plate like. D. Microvilli covered cells from the intestines. Microvilli are tiny hair like protrusions in the plasma membrane of intestinal cells that increase the absorption of nutrients in the intestines.arrow_forwardOne important biological effect of a large dose of ionizing radiation is to halt cell division. What might be the effects of such a mutation if the cell is not irradiated?arrow_forward
- In mitosis, why do the chromosomes need to condense in prophase and line up in metaphase? (To be clear, this is asking about the usefulness of these specific actions, not just that those things need to happen as part of the overall process.)arrow_forwardThe “Hayflick limit” is the number of times cells growing in tissue culture will divide before cell proliferation ceases. What experimental procedure can be employed to remove this limit?arrow_forwardA cell has 30 chromosomes before mitosis. After the completion of mitosis, the two daughter cells would have how many chromosomes in EACH? a). 30 b). 20 c). 15 d). 60arrow_forward
- Sometimes a cells "deal with" damaged DNA by just killing off the cell. This special cellular suicide is called apoptosis. Usually, the cell cycle has checkpoints that prevent damaged/mutated cells from proceeding to the next phase, though. When these checkpoints don't work, apoptosis can be used. If apoptosis did NOT occur, how might the damaged DNA impact the rest of the cell cycle? A. it may not complete the cell cycle correctly B. new cells containing damaged DNA may be made C. the cell may enter G0 D. all of the above are options E. A and B, but not C F. B and C, but not Aarrow_forwardOne important biological effect of a large dose of ionizing radiation is to halt cell division. How does this occur?arrow_forwardOncologists (cancer doctors) frequently measure the mitotic index of tumor cells when they are removed via surgery or biopsy. What do you think is the value of finding out the mitotic index of these cells?arrow_forward
- 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.arrow_forward1) 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.
