Class notes BIOS 1700: Ch.11- Cell Division

Chapter 11 notes answers: How can we produce trillions of cells with identical genetic information? How do we pass on our genes to the next generation? What genes can cause or prevent cancer? What would happen if cyclins stay active all the time in the cell? What would happen if the cell loses one of the cyclin genes? What is MPF? How did scientists discover cell cycle regulators, including cyclins? What are the major differences between mitotic and meiotic divisions? While also hitting the main concepts: Mitotic cell division (chromosomes), meiotic cell division, cell division in prokaryotes (binary fission) and eukaryotes (mitotic cell division), prokaryotic and eukaryotic genome, mitotic cell division (cytokinesis after mitosis) in plants/animals, detailed description of prophase 1, detailed description of meiosis I and II, mitotic vs. meiotic cell division (5-star summary), developmental differences between female and male germ-line (sex) cells, genetic variation in chromosomes (the loss or gain), the causes of abnormalities (chromosome nondisjunction), the discovery of cell cycle regulators (cyclin), CDK cycle, the p53 tumor suppressor gene, and the progression of cancer. This document also contains drawings of diagrams for a better understanding of concepts.
