1. Describe the process of binary fission. What type of organisms have this reproduction? Differentiate between the prokaryotic and eukaryotic chromosomes Explain why and how DNA coils up into chromosomes. Name the phase of the cell cycle where DNA replication takes place. Why is this process important in cell division? Explain what happens during: G1 phase, M phase, metaphase, telophase.

2. List the phases of mitosis and the main purpose of this process Identify the stages of mitosis on the following cells:

3. List all learned external regulators of the cell cycle. List all internal regulators of the cell cycle. What is the role of checkpoints in the cell cycle? What happens when the cell regulation of the cell cycle does not work properly? Name the stages of mitosis:

4. Determine the shape and number of chromosomes and the number of chromatids if the chromosome number of the species is 56 In G1 G2 S (end) Prophase Metaphase Anaphase During cytokinesis in each nucleus

5. What are the characteristics of cancer cells? List the stages of cancer Differentiate between benign and malignant tumors.

6. Describe what the main purpose of mitosis and cytokinesis is. What type and how many daughter cells are produced by mitosis? Differentiate between haploid and diploid cells. Define what homologous chromosomes are Name cells in your body that would be haploid Name cells in your body that would be diploid. List three internal regulators of the cell cycle. Describe them. Describe what happens if the cell cycle regulation fails. Name three characteristics of cancer cells.

7. Determine the number of chromosomes/chromatids if the diploid chromosome number is 20 Number of chromatids in a diploid cell during G2 Number of chromatids in a diploid cell during G1 Number of chromosomes in a haploid cell Number of chromatids in a haploid cell after S phase

8. Number of chromatids in a haploid cell after mitosis Number of chromosomes in a diploid cell after mitosis. Number of chromatids in a diploid cell during prophase (beginning of mitosis) Number of chromatids in a haploid cell during prophase
