Below are images taken at different time points of a cell undergoing mitosis. You do not need to know the names of the phases of mitosis. But we walked through the main events during mitosis (simple cell division) as they affect how sister chromatids of replicated chromosomes are moved into the two daughter cells to produce two genetically identical daughter cells. Note: Dyes were used to stain DNA red, while spindle fibers (and other microtubules) are stained green in these images.

Use your knowledge of what occurs during mitosis to determine in which stage the following steps occur. Nucleus disappears Daughter chromosomes are formed Daughter cells form Sister chromatids split Chromosomes align at equator Chromatin condenses into chromosomes Spindle fibers attach to chromatids Spindle fibers begin to form Nucleus reappears Prophase Metaphase Anaphase Telophase
Sri K.
Put the phases of mitosis in the correct order based on their descriptions Interphase chromosomes align at the central metaphase place spindle fibers appear; chromosomes begin to appear sister chromatids are pulled apart towards opposite sides of the cell nuclear membrane forms around single chromosomes at opposite poles of the cell cytoplasm divides and original parent cell forms two new; identical cells spindle fibers attach to chromosomes at their centromeres
Suman K.
Each of the following descriptions occur during mitosis or under cytokinesis. Write the name of the phase for each 2. Chromosomes decondense to chromatin 3. Chromosomes become visible and consist of two sister chromatids attached at the centromere. 4. Cell is "pinched" into two cells 5. Nuclear envelope begins to disintegrate. 6. Sister chromatids separate and move toward opposite poles 7. Spindle fibers disappear 8. Nuclear envelope reforms 9. Centrioles move to opposite poles of the cell. 10. Microtubules (spindles) extend and attach to the centromeres. 11. Chromosomes move to the middle
