Stages of Mitosis Answer the following questions: 1. Which stage does each of the following occur? ● Chromatin condenses into chromosomes Chromosomes align in center of cell. Longest part of the cell cycle. ● Nuclear envelope breaks down. . Cell is cleaved into two new daughter cells. Daughter chromosomes arrive at the poles. Chromatids are pulled apart 2. Answer the following questions. You can review the steps of mitosis using the following online activity https://www.oppia.org/explore/q4NBr1JG7Qrt: ● ● ● ● How many chromosomes are visible at the beginning of mitosis? • How many are in each daughter cell at the end of mitosis? • ● The little orange T shaped things on the cell are: What happens to the centrioles during mitosis? 3.

Biologists have long been interested in the effects of radiation on cells. In one experiment, researchers examined the effect of radium on mitosis of chick embryo cells growing in culture. A population of experimental cells was examined under the microscope for the number of cells in telophase (as a measure of mitosis occurring) before, during, and after exposure to radium. The results are shown in the Figure. What is the effect of radium exposure on mitosis? Source: R. G. Canti and M. Donaldson. 1926. The effect of radium on mitosis in vitro.

Read the discussion of the cell cycle, mitosis, and cytokinesis, pages 00-4to7.In the table below, describe briefly the major events of each part of the cell cycle. (You might want to turn the table sideways so you can write the long way in each box.) Interphase M phase (mitotic cell division) G1 G2 Mitosis Cytokinesis S Prophase | Metaphase Anaphase Telophase
Review the events associated with each stage of mitosis in addition to the preparatory stage, interphase. List these events in table. Some events and structures occur only in plant cells and some occur only in animal cells. Mark these events in your list with an asterisk. This list can serve as an excellent study guide, so be as complete as possible. Interphase Prophase Prometaphase Metaphase Anaphase Telophase
Mitosis in animals is responsible for the formation of what type of cells? (select all the apply)" Somatic Cells Egg Gametes Germ Cells Sperm Sex Cells Body Cells Zygote What is occurring in the image below and what cell division process does this occur in? Recombinant chromatids
Please briefly describe the steps of MITOSIS here using diagrams, illustrations, and information from the internet or your text to help with your description..…include in your discussion the steps: Interphase; Prophase; Metaphase; Anaphase; and Telophase where needed
Indicate the stage of mitosis (interphase = I, prophase = P, metaphase = M, anaphase = A, telophase = T) during which each of the following events occur. chromatid doublets separate to individual chromosomescentriole replicatesreplicated chromosomes (chromatid doublets) are arranged in single file next to one another at the cell's equatornuclear membrane is disappearingspindle fibers form and become visiblecell plate (plant) or cleavage furrow (animal) forms and is visiblechromosomes are at opposite poles of the cell; cytokinesis is almost completedchromosomes (chromatids) first become visible as long thin strandsDNA (chromosome) replication occurs
mitotic index: Interphase = 80 cells Prophase = 9 cells Metaphase = 5 cells Anaphase = 2 cells Telophase = 4 cells The average duration for the cell cycle in this culture is known to be 20 hours. Use the data above to work out the duration of interphase and metaphase.
Please help Place the images of the cell division in the right order and label them a) What is the final product of this type of cell division? Indicate the number of dauahter cells, the TYPE OF CELLS (somatic cells? sex cells? other?), where in the body this process takes place, whether they are genetically diverse pridentical, haploid or diploid, the chromosome number in human cells, whether they contain sinale- or double-stranded chromosomes, and what the "fate" of these cells is i.e. what will they go on to do, if given the chance)?
PLEASE ANSWER THE FOLLOWING QUESTIONS: 1. In figure 1 locate the mitotic zone or region of cell division. Next, identify mitotic stages visible in figure 2. Note down visible structural changes occurring at various stages of mitosis, namely: prophase (early and late) metaphase, anaphase (early and late) and telophase (early and late). 2. Point the specific mitotic stages that can be seen in the enlarged image of onion root tip cells undergoing cell division (figure 2). 3. Search for a diagrammatic illustration of the different stages of meiosis, examine/study carefully the changes occurring in each stage. Note how these stages assemble or differ from those of mitosis. 4. Then, summarize the structural changes occurring in each stage of mitosis and meiosis in a tabular form.
