Transcript of Biology 2: Chapter 10.1 and 10.3 reteach

Cathy Jun Cell Reproduction and
Regulation Reteach Why do Cells Divide? - Cell Size
- Cell Maintenance
- Making New Cells How do Cells prepare for Cell Division? - DNA is copied
- Cell begins to divide
- Cell completely divides
- 2 Identical cells Factors that control cell growth - Protein signals and other environmental signals How is DNA packaged into the nucleus? Prokaryotes - Single circular molecule of DNA
- Prokaryotic chromosome is condensed through repeated twisting or winding Eukaryotes - Packaged into highly condensed chromosome
- Histones -> 8 Histones = Histone Core -> Histone Core + Long DNA molecule = Nucleosome -> 30nm -> Chromatid-> Daughter Cell - Each daughter cell must contain enough of each organell
- DNA must be copied, sorted and separated Prokaryotes Eukaryotes How do Feedback Signals Affect the Cell Cycle? - Feedback signals at key checkpoints in the cell cycle can delay or trigger the next phase of the cell cycle How can Cancer relate to the Cell Cycle? - Uncontrolled cell growth and division can result in masses of cells that invade and destroy healthy tissues Cell Reproduction Cell Regulation
