TAILIEUCHUNG - Lecture AP Biology - Chapter 12: The cell cycle

After completing this unit, you should be able to: Describe the structural organization of the prokaryotic genome and the eukaryotic genome; list the phases of the cell cycle; describe the sequence of events during each phase; list the phases of mitosis and describe the events characteristic of each phase;. | Warm up Define: genome, gametes, chromatin, chromosome, centromere, kinetochore, checkpoint, Cdk, MPF What is the longest part of the cell cycle? Why? If the diploid number is 46, the haploid number is? Ch. 12 Warm up At the end of mitosis and cytokinesis, how do daughter cells compare with their parent cell when it was in G1? A cell’s DNA was measured at 5 picograms. DNA levels range from 3-6 pgms in the cell cycle . What stage of the cell cycle is this cell in. How do you know? At metaphase, if the haploid number is 3, how many chromatids does this cell have? Ch. 12 Warm up What is the correct phase of the cell cycle/mitosis for the following: Most cells that no longer divide or rarely divide are in this phase Sister chromatids separate and move apart Mitotic spindle begins to form Cell plate or cleavage furrow form Chromosomes replicate Chromosomes line up on equatorial plate Nuclear membrane forms Chromosomes become visible Ch. 12 Warm up Describe the difference between plant and animal cell division. Measurements of the DNA amount per nucleus were taken. DNA levels ranged from 3-6 picograms per nucleus, what stage of the cell cycle are these cells in? One nucleus has 3 pgrms One with 6 pgrms 5 pgrms Describe binary fission. Ch. 12 Warm up How do we know the cell uses chemical signals? Summarize the cell control system. Compare a cancer cell to a normal cell. What goes wrong? Ch. 13 Warm up Compare sexual to asexual reproduction. Compare/contrast mitosis to meiosis. Describe the events of meiosis. Ch. 13 Warm up Describe and compare the 3 sexual life cycles How does random assortment, crossing over and random fertilization contribute to genetic variation? Define: locus, karyotype, alternation of generations, synapsis, tetrad, chiasmata Chapter 12: The Cell Cycle What you must know: The structure of the duplicated chromosome. The cell cycle and stages of mitosis. The role of kinases and cyclin in the regulation of the cell cycle. Cell Cycle: life of a cell
