Answer:- Drugs/chemicals that affect the movements of chromosomes during mitosis affect normal cell division, called mitotic inhibitors.
Explanation:- mitotic inhibitors disrupt microtubules
(structures that pull the chromosomes apart during cell
division).
- Mitotic inhibitors are used in cancer treatment, because cancer
cells are able to grow and last spread through the body through
continuous uncontrolled mitotic division.
- Thus, cancer cells are more sensitive to inhibition of mitosis
than normal cells.
How would factors (drugs/chemicals) that affect the movements of chromosomes during mitosis affect normal cell division...
Why are chromosomes in their chromatin form prior to mitosis (during interphase)? Why would DNA wind tighter around histones prior to the start of mitosis? Is cancer caused by errors during mitosis or is it caused by something else? Hint: why is it so difficult to treat cancer? How do bacterial cells reproduce? How does it compare to eukaryotes (what’s the same /different)?
3. Draw a cell with three chromosomes as it moves through mitosis and cytokinesis. 4. Draw a cell with three chromosomes as it move through meiosis and cytokinesis. 5. Why are some cancers heritable and some are not? What is an example of a type of cancer that might be inherited and an example of one that is not? 6. Describe how chemotherapy, radiation, and immunotherapy are used to treat cancer. Describe how cancer cells look and act different than...
3. Many chemotherapy drugs used to treat cancer work by modifying the mitotic spindle. Given the short description of the two drugs here, describe how these drugs are effective in stopping cancer cells and where in the cell cycle they are effective. Paclitaxel works by interfering with normal microtubule breakdown during cell division and Vinblastine works by binding tubulin, thereby inhibiting the assembly of microtubules. 4. A researcher has developed three different cell lines that are able to each ignore...
How many chromosomes and chromatics would a typical human cell have after duplication but before mitosis? 0 46 chromosomes, 92 sister chromatids o 23 chromosomes, 46 sister chromatids 46 chromosomes, 46 sister chromatids O 23 chromosomes, 23 sister chromatids
3) A cell in prophase II of meiosis contains 12 chromosomes. How many chromosomes would be present in a cell from the same organism if it were in prophase of mitosis? Prophase I of Meiosis?
If the original mother cell is a human skin cell, how many chromosomes would each of the 2 daughter cells contain at the end of mitosis and cytokinesis? In humans, somatic cells contain 46 chromosomes organized into 23 pairs.
9. Blue whales have 44 chromosomes in every cell. Determine how many chromosomes you would expect to find in the following: i. Sperm Cell: ii. Egg Cell: ili. Daughter Cell from Mitosis: iv. Daughter Cell from Meiosis II:
Assignments, Chapter 2, Drugs and the Body Learning Objective(s) Written Assignments 1. Drugs affect the cell function in a variety of ways. Briefly describe and provide an example of an agonist, a competitive antagonist, and a noncompetitive antagonist. 2. The process of dynamic equilibrium determines drug concentration in the body. Describe how the phases of absorption, distribution, metabolism, and excretion impact drug concentrations. Learning Objective Group Assignment 1. As a group, list factors that can influence the effectiveness of drugs...
The picture below represents a cell during metaphase of mitosis. The chromosomes are represented in red and the mitotic spindle is represented in green. BO ! A. The cell is stuck in metaphase because a checkpoint has been activated. Why was the checkpoint triggered? B. What could have happened to this cell without this checkpoint? There are three main checkpoints during the cell cycle. One checkpoint occurs at the end of G1 phase and involves the protein p53. If p53...
If a nucleus has 64 chromosomes during interphase (G1), how many sister chromatids would it have at the beginning of mitosis? How many chromosomes would each of the daughter cells have after mitosis is complete?
