Answer: Dire wolves belong to class Mammalia. The mammalian cells have 2n or a diploid number of chromosomes. If dire wolves have five pair of chromosomes (2n=5) in their cells, then at the end of Anaphase II there will be five pair of chromatid also. For example; In the case of Human, The number of chromosome is 46 or 23 pairs (2n-23). a chromosome consists of two sister chromatids. Therefore, The correct answer is B, at the end of anaphase II number of chromatid will be 5 not 0.
| Meiosis | No. of chromosomes | No. of Chromatids | Division Phase |
|---|---|---|---|
| Prophase I | 46 | 92 | (Phase I) At the end of Meiosis, I = 23 number of chromosomes and 46 no. of chromatids. |
| Metaphase I | 46 | 92 | |
| Anaphase I | 46 | 92 | |
| Telophase I | 46 | 92 | |
| Prophase II | 23 | 46 | (Phase II) (Phase I) At the end of Meiosis- II = 23 number of chromosomes, and 23 no. of chromatids. |
| Metaphase II | 23 | 46 | |
| Anaphase II | 46 | 46 | |
| Telophase II | 46 | 46 |

2. Explain why the replication of one of the DNA strands is continuous while the other strand is discontinuous. What causes this difference? 3. A) What are telomeres? B) Are telomeres present in both Prokaryotes and Eukaryotes? Explain why some cells have telomeres and others don't. 4.

d. The images in panel d below show normal anaphase (first row) and anaphase in cells where dynein is not localized to the cell membrane. The chromosomes are fluorescently labeled. The kymograph in panel e shows the same data as in panel d (separation of sister chromatids durin anaphase). As you can see, if dynein is mislocalized, the chromosomes do not separate as mu the wild type control. Based on your knowledge of how dynein acts normally in anaphase B...
