Onion root tips are stained to identify the various stages and duration of mitosis. Students will also have an opportusnity to analyze mechanism involved with loss of cell cycle control in cancer. Meiosis and Crossing Over in Sordaria is also examined in this experiment.  \nEVTAP07.121213  \nEXPERIMENT  \nAP07 Cell Division: Mitosis and Meiosis  \nTable of Contents  \nPage  \nExperiment Components 3  \nExperiment Requirements 3  \nBackground Information 4  \nExperiment Procedures  \nExperiment Overview 12  \nInvestigations I & IV: Modeling Mitosis and Meiosis 13  \nInvestigation II: Studying the Effects of Environment on Mitosis 17  \nInvestigation III: Loss of Cell Cycle Control in Cancer 19  \nInvestigation V: Meiosis and Crossing Over in Sordaria 22  \nStudy Questions 23  \nInstructor’s Guidelines  \nNotes to the Instructor 25  \nPre-Lab Preparations 26  \nExperiment Results and Analysis 28  \nStudy Questions and Answers 32  \nMaterial Safety Data Sheets 34  \nThe Advanced Placement (AP) Program is a registered trademark of the College Entrance Examination Board.

It is remarkable when one considers that as individuals we have all arisen from the fertilization of a single egg with a single sperm. From this single cell we develop into unique individuals with highly differentiated tissue types. The instructions for the precise timing of development, growth and maturation are all contained within DNA, which is organized as nucleotides encod","cbCaiuIS1Z6xs8md","https://ap.wps.com/l/cbCaiuIS1Z6xs8md","pdf",2558915,33,"English","# Experiment Components\n## Investigations I & IV\n## Investigations II\n## Investigations III\n## Investigations V\n# Experiment Procedures\n## Experiment Overview\n## Investigation I & IV: Modeling Mitosis and Meiosis\n## Investigation II: Studying the Effects of Environment on Mitosis\n## Investigation III: Loss of Cell Cycle Control in Cancer\n## Investigation V: Meiosis and Crossing Over in Sordaria\n# Study Questions\n# Instructor’s Guidelines\n## Notes to the Instructor\n## Pre-Lab Preparations\n## Experiment Results and Analysis\n# Study Questions and Answers\n# Material Safety Data Sheets","[{\"question\":\"What is the main goal of this experiment on cell division?\",\"answer\":\"Students identify and differentiate stages of mitosis and meiosis.
