M ITOSIS OUTLINE : A N APPROACH TO STUDYING FOR MITOSIS LECTURES Read chapter 9 ; focus on what happens to the DNA in terms of replication, and the phases of mitosis. Do not focus on any of the biochemistry or mechanisms controlling DNA replication, coiling, etc. I want you to understand: What is the function of mitosis? Where do we see it? Cell division Development Reproduction (asexual) Mitosis is part of the Cell cycle: What is the cell cycle Basic Cell cycle phases: What happens in each? Gap 1 Synthesis Gap 2 Mitosis Phases of the cell cycle differ in how DNA is coiled: Why? When is DNA: Uncoiled – Chromatin form Coiled – Chromosomes seen Not to worry about: details of how chromosomes are coiled around histone proteins How does the cell prepare for mitosis?

Unformatted text preview: DNA replication occurs when? What are chromatids ? What are centrosomes and when do they replicate? What happens in Gap 2 with centrosomes and spindle fibers ? Not to worry about: triggers for cell to start reproducing; biochemistry of processes What are the Phases of Mitosis, and what happens in them? Prophase Prometaphase Metaphase Anaphase Telophase What happens to the DNA in each phase? When are the chromatids attached to each other and when do they separate? Think about how many pieces of DNA are present and how much genetic information (= unique chromosomes) is present in each phase and in interphase What happens with the nuclear membrane and with cell division ( cytokinesis )?...
