1/24 Bell Work: Add to assignment #3 __Cell Cycle__ A. The cell cycle is the process by which one cell becomes two cells. B. The three stages of the cell cycle are interphase, mitosis, and cytokinesis. C. During interphase, the cell grows and makes a copy of its DNA. D. Mitosis produces two identical nuclei. E. A cell’s cytoplasm and organelles are divided between the two new cells.

Class activity preparing for the quiz Friday. Cell Cycle Review Questions When an organism grows, what happens to its cells? More cells are produced by cell division. How does an organism replace damaged cells? A cell nearby divides to replace the damaged cell. What is the process of cell growth and division called? The Cell Cycle What is the purpose of the cell cycle? Why is it done? growth and repair What are the three stages of the cell cycle? Interphase, mitosis, and cytokinesis. What happens during interphase? A copy of the cells DNA is produced. What happens during replication? A copy of the cells 46 pieces of DNA is produced. What happens during mitosis? The two copies of the DNA are separated into two new nuclei. What happens during cytokinesis? The cell's cytoplasm divides. What do the paper pieces that we are cutting out represent? Bases of a DNA model What process will be demonstrated with the DNA model? replication

Use the model.
