Mike Clark, M.D.. The . cell cycle. , or . cell-divisional cycle. , is the series of events that take place in a cell leading to its division and duplication (replication). . In cells without a nucleus (prokaryotes), the cell cycle occurs via a process termed binary fission. . Why do cells need to divide?. Growth and development. You started as 1 cell and now you’re made up of roughly 40 TRILLION cells. Repair and regeneration of tissue. Reproduction. What happens when cells divide? . The . cell cycle. , or . cell-divisional cycle. , is the series of events that take place in a cell leading to its division and duplication (replication). . In cells without a nucleus (prokaryotes), the cell cycle occurs via a process termed binary fission. . Topic 1: DNA Organization. By the end of this topic, you should be able to…. Identify parts of a chromosome. Explain why DNA has to copy and coil before cell division. Explain why cells cannot continue to grow forever. DNA damage DNA gets damaged a lot ! DNA damage DNA gets damaged a lot! >200,000 events/human cell/day DNA damage Occurs 2 ways 1) spontaneously 2) mutagens : damage DNA Transposons Discovered by Barbara McClintock 1. How many phases are in the cell cycle as shown in the diagram in Model 1?. Four.. 2. Starting at the starred cell, what is the order of the stages of a cell’s life?. G1, S, G2, M.. 3. During which phase does the size of the cell increase?. The . cell cycle. is a repeated pattern of growth and division that occurs in eukaryotic cells. . This cycle consists of three phases: G1, S, G2. The first phase represents cell growth while the last two phases represent cell division.. 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. Cell Cycle AnalysisUWCCC Flow Cytometry Laboratory 1111 Highland Ave7016 WIMRMadison, WI 608.263.0313 OverviewThe cell cycle profile of a sample can be determined by staining the DNA Useful Reference Variation of length of cell cycle. In humans, the frequency of cell turnover . varies. E. arly embryonic development. (Few hours ). E. pithelial cells (2-5 days). Specialized cells. (. cortical neurons or cardiac muscle cells. 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. General Biology. Name. ________KEY_______________________. Reproduction. All Cells come from other cells (. Remember the cell theory?. ). Asexual – Organisms formed by only one parent; offspring are identical; fast; fine for environments that don’t change frequently since each organism is a clone.
