NADIR R. FARID INTRODUCTION Most tumor suppressor genes (whose function in cancer biology was surmised by their inactivation or deletion) turn out to be important in normal cell growth and the Cell Cycle. 10.3.

Restate what happens in each stage of the cycle.. Vocabulary. Cell . cycle. Interphase. Mitosis. Cytokinesis. Cells . Live in a Cycle. . During the cell cycle, a cell grows, prepares for division, and divides to form two identical daughter cells, each. of which then begins the cycle again.. The series of events that cells go through as they grow and divide.. Cell Cycle - a cycle of growth, development, and division. This is how organisms grow, produce new cells, and replace old cells. The cell cycle occurs in 2 phases: Interphase and . Mitosis. The Cell Cycle: Interphase. Unit 1 – Cells and Proteins. Advanced Higher Biology. Miss Aitken. Why is controlling the cycle important?. Complex events must work perfectly to produce new daughter cells. Mutations can occur if events do not go to plan. It is the growth and division of single cell into daughter cells and duplication (replication).. In . prokaryotic cells, . the cell cycle occurs via process termed binary fission..
