Updated Mitosis Video. The Amoeba Sisters walk you through the reason for mitosis with mnemonics for prophase, metaphase, anaphase, and telophase. Expand details to see table of contents.? Video handout here: http://www.amoebasisters.com/handouts Table of Contents: Why is Mitosis Important? 0:44 Why Don't You Want Cells Dividing all the Time? 2:00 Interphase (occurs before mitosis) 2:23 DNA and Chromosomes 2:55 Chromosome Replication 4:07 PMAT Mitosis Stages 5:30 Cytokinesis (actual splitting of cell) 7:30 We appreciate the feedback we get for what we need to clarify or should have added. Here is a clarification (also pinned in comments): We mention mitosis as "a type of cell division." To be more specific, it's a division happening within the cell---in the nucleus. But we do not introduce the nucleus until later on in video. Mitosis is specifically the division happening of the nucleus whereas cytokinesis follows to do the actual splitting of the cell (cytokinesis at 7:30). Some so
