Question

Exercise 8: Post-Laboratory Exercise Name: TAL . Section Part B: Fill-in-the-Blanks .1. During what stage of the cell cycle does DNA replication occur? 2. Name the phase of cell division when separation of sister chromatids occurs. 3. By what process does the cytoplasm of a human cell separate? 4. Name the phase of cell division when duplicated chromosomes first appear 5. Where in humans would you expect to find meiosis taking place? 6. What do you call chromosomes that look alike and carry the same type of genetic information? 7. If homologues are separating, what phase is this? 8. Name the type of cell division described by 2n 2 9. Does metaphase of mitosis, meiosis I, or meiosis II have the haploid number of chromosomes at the equator of the spindle? Part C: View Meiosis Under the Microscope. View the meiosis slide. First find a cell representing interphase, locate the remaining four stages of meiosis I cell division and the four stages of meiosis I cell division. Draw one of the stages. Make sure to label it correctly Stage TA Signature: Part D: TA Signature for the completion of Exercise 8A, 8B, 8C, 8D, and SE: art E: TA Signature for cleaning your table after pop bead exercise:

Explanation / Answer

1. During S phase of the cell cycle DNA replication occurs.

2. Anaphase. During Anaphase of cell division separation of daughter chromatid occurs.

3. Cytokinesis: by cytokinesis human cell cytoplasm separate.

4. Prophase; during Prophase duplicated chromosome first appears.

5; In Testes , specifically in Spermatogonia . Here we expect to find meiosis going on.

6 . Homologous chromosomes. They look alike and carry same type of genetic information.

7. Anaphase of meiosis - I . During Anaphase of meiosis-l homologous chromosomes separate.

8. Mitosis.

9. Metaphase of meiosis-ll has haploid number of chromosome.

Hopefully it helps thanks.
