What about a cell that had 10 chromosomes? 3. What 3 components do all life cycles have in common? 4. Does synthesis of DNA happen during mitosis? 5. What do we know about bacterial chromosomes? 6. Discuss the amount of DNA and the number of chromosomes in a cell in G2 vs one of the cells at the end of Meiosis II. 7. In which phases do we find chromosomes composed of 2 chromatids? 8. In meiosis, when do sister chromatids separate? 9. If mitosis occurred without cytokinesis, what would the result be? 10. Explain the 3 checkpoints in the cell cycle. 11. If a cell has 6 chromosomes at metaphase how many will it have in anaphase?
