Exercise 3 Modeling Meiosis In this exercise, you will create models to simulate the stages of meiosis in an animal cell. Procedure 1 Gather the chromosome kit, 2 sheets of white paper, 2 sheets of black paper, cut pieces of drinking straw from Exercise 1, scissors, tape, and the digital camera. 2 Create the cell body by taping 2 sheets of white paper together. 3 Create 4 nuclei by cutting 4 circles from the black paper, approximately 6" in diameter. 4 Create a set of chromosomes ("original" and "duplicated"), as shown in Table 3. When building the chromosomes, the white magnetic tube represents the centromere, while the beads extending from the centromere represent the arms. Note: The colors and numbers of beads per arm is the same as created in Exercise 1.

When meiosis II begins, there will be 2 cells (the pieces of paper will be separated from one another).

Transcribed Image Text:Exercise 3 Modeling Meiosis
In this exercise, you will create models to simulate the stages of meiosis in an animal cell.
Procedure
1 Gather the chromosome kit, 2 sheets of white paper, 2 sheets of black paper, cut pieces of drinking straw from
Exercise 1, scissors, tape, and the digital camera.
2
Create the cell body by taping 2 sheets of white paper together.
3
Create 4 nuclei by cutting 4 circles from the black paper, approximately 6" in diameter.
4
Create a set of chromosomes ("original" and "duplicated"), as shown in Table 3. When building the
chromosomes, the white magnetic tube represents the centromere, while the beads extending from the
centromere represent the arms.
Note: The colors and numbers of beads per arm is the same as created in Exercise 1.
