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?
You add a chemical to five samples of cells and have another five samples of cells to which you do not add the chemical. You wait 10 minutes and then stain all ten samples of cells and observe if they have entered mitosis or not?
What is the dependent variable?
Group of answer choices
A) If the cells entered mitosis or not
B) The number of samples of the cells
C) The length of time before stainingg
D) If the cells are treated with the chemical or not
List at least five (5) significance of mitosis.

- The phases of mitosis are shown in Figure 6.4. Mitosis is the type of nuclear division that occurs when an animal or plant grows larger and when injury heals. Two daughter cells result because there is only one round of division, and it keeps the chromosome number constant (same as the parent cell). The prophase cell in Figure 6.4 has the same number of chromosomes as the telophase nuclei in Figure 6.4. Explain the different appearance of the chromosomes.arrow_forwardOne important biological effect of a large dose of ionizing radiation is to halt cell division.
