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. MaterialStorageStabilityTali Cell Cycle SolutionRoom temperatureDO NOT FREEZEProtect from lightWhen stored as directed, kit components are stable for at least 6 months.Number of reactions: Sufcie Identify and restate what the phases of the eukaryotic cell cycle are.. Restate what happens in each stage of the cycle.. Vocabulary. Cell . cycle. Interphase. Mitosis. Cytokinesis. Cells . Live in a Cycle. 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. The cell cycle, or cell-division cycle, is the series of events that takes 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 . Chapters 12, 13, 16, 17. Limits to Cell Growth. The larger a cell becomes, the more demands a cell places on its DNA. If extra copies of DNA are not made, an “information crisis” would occur. The cell also has more trouble moving nutrients and wastes across the cell membrane. Alexey Khodjakov. Wadsworth Center. Genet. Mol. Biol. vol.22 n.4 São Paulo Dec. 1999.
