3. Mitosis for 100 Name the five phases of the cell cycle in order (excluding cytokinesis). Interphase, Prophase, Metaphase, Anaphase, Telophase

4. Mitosis for 200 During which phase does the DNA uncoil? Telophase

5. Mitosis for 300 How many versions of each gene are present during prophase? Four. There was already one from each parent before DNA replication.

6. Meiosis for 100 Why does meiosis occur? Meiosis occurs only to produce gametes (sperm cells and egg cells) in animals.

7. Meiosis for 200 What cells are byproducts of oogenesis, and what happens to them? Polar bodies are reabsorbed by the ovaries.

8. Meiosis for 300 List the number of autosomes and the number of sex chromosomes in a human ovum. 22 autosomes and 1 sex chromosome because the ovum is just a haploid gamete.

9. Potpourri for 100 Daily Double! What’s your wager? List three differences between mitosis and meiosis.

10. Potpourri for 200 How many ____ in a nerve cell? A) C hromosomes46 B) G enesabout 30,000 C) B ase pairs of DNAabout 6 billion

11. Potpourri for 300 At what specific point in cell division is DNA no longer able to function? This occurs in prophase when the DNA supercoils. Compact DNA is as unreadable as a closed book.

12. No calculators allowed! How many cells would one ideally expect after four hours and 15 minutes if seven Bacillus megaterium carried out binary fission every 30 minutes? Binary fission would be able to complete only 8 times in the 255-minute timespan. We start with seven cells, so we have the following expression: 7 * 28 = 7 * 256 = 1792
