Advanced Key Concepts After the mitosis & meiosis lectures, students should be able to:  Summarize the importance of mitotic & meiotic cell division to living organisms.  Describe the function, and compare proto-oncogenes, oncogenes, and tumor suppressor genes.  Describe the three checkpoints the cell monitors before proceeding through the cell cycle and describe the molecular mechanisms the function at each checkpoint.  Analyze disruptions in cell cycle regulatory mechanisms, and predict their impact on progression of the cell cycle and relevance to human health.  Describe levels of chromosome compaction during phases of the cell cycle.  Relate chromosome copy number and structure to phases of the cell cycle.  Summarize similarities and differences of meiosis I and meiosis II.  Relate the impact of crossing over to chromosome structure and genetic variation.  Compare and contrast the process and results of mitosis and meiosis. Vocabulary Be able to define, identify, and (where appropriate) name the function of the following:  Binary fission  Origin (of replication)  Terminus  Chromosome  Homologous chromosome; homologue  Chromatid, sister chromatid  Histone
