Let’s model mitosis. Focus on drawing the cell nucleus taking care to model the number and location of chromosomes. Although the chromosomes are only visible in each stage, draw them in all stages for clarity sake.
Draw a 2n=4 cell at G1 of interphase.
Draw the same cell at the start of prophase.
Draw the same cell at metaphase.
Draw the cell(s) that result at the end of cytokinesis.

You will start each section with a cell with the same number of chromosomes so you can see the differences that happen as it goes through one process versus the other. Part 1 - Mitosis: Draw the steps of mitosis for a cell that has 8 chromosomes. You do not have to write anything other than to label which step you are showing with each drawing. I mostly want the big 4 steps, but you may include Interphase and Cytokinesis if you want.arrow_forwardCell Cycle: Mitosis The Cell Cycle and M Mitosis Worksheet The diagram below shows six cells in various phases of the cell cvcle.

These toxins can be used in many different ways – some of them are used during scientific research to arrest the cell cycle at specific points so that the cells can be studied. Others have clinical applications as chemotherapeutic drugs that are useful in the treatment of cancer, as well as other types of disease. Study the list of toxins below, and use the information provided and your understanding of mitosis to answer the questions below. Note: some of these drugs are currently approved for clinical use, while others are still in development. For the purposes of this exercise, assume that all of them are available for use.

You will also view an onion root tip and calculate the percentage of cells at each of the stages of cell division. 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.
