Step by step
Solved in 3 steps
- a. Give an illustrated account of mitosis, to show how two genetically identical cells are produced. b. Give two differences between mitosis and meiosis.Draw or explain in a simple manner what needs to be done in each step of modeling mitosis. Steps/ Procedure: 1. Tie the ends of a 10-ft (3-m) piece of string together and form a circle on the table. This represents the cell membrane of a parent cell. 2. Make a smaller circle from a 5-ft (1.5-m) piece of string to create a nuclear membrane, and place it inside the cell membrane. 3. Place 1 sock of each pair into its mate and jumble the socks inside the nuclear membrane. 4. During interphase, the cell prepares for nuclear division and DNA replicates. To simulate replication, remove a mate from each pair of socks. Match sister chromatids and connect them at their centromere by tying the matching pairs together at their centers with a small piece of string. Place them back into the nuclear membrane, jumbling them up. 5. Mitotic division now begins with prophase. During this phase, DNA condenses into chromosomes made up of 2 identical sister chromatids, and the nuclear membrane breaks…Directions: Complete the illustrations that show the differences between mitosis and meiosis. Consider the two-winged fly species Cricotopus sylvestris with chromosome number 2n = 4. Draw the stages (prophase, metaphase, anaphase and telophase with cytokinesis) of the two cell divisions in the corresponding boxes of Table 1. No need to include prometaphase. One box is to one stage. For each stage, draw clearly the appearance and configuration of the cell(s) and the chromosomes. Inspect and refer to slides 10 to 11 of the Cell Division PPT for mitosis and slides 14 and 17 for meiosis. Make sure that when the pictures are zoomed in, they will still be clear. For better illustration, draw the chromosomes with different sizes (inspect and refer to slides 10 to 11 of the Cell Division PPT for mitosis and slides 14 and 17 for meiosis). Use one color for the chromosomes in mitosis and two colors for the chromosomes in meiosis (see slides 10 to 11 of the Cell Division PPT for mitosis and…
