What events characterize prophase, metaphase, anaphase, and telophase in mitosis?

Mitosis is basically the way our cells make copies of themselves, and honestly, it’s wild how precise it has to be every single time. In prophase, the chromatin starts to condense into visible chromosomes, and the nuclear envelope just sort of breaks down so the cell can get to work. It’s the prep stage where the spindle fibers start forming, setting the stage for everything else to happen.

When you get to metaphase, those chromosomes line up right in the middle of the cell, which we call the metaphase plate. It’s like they’re all taking their positions before being pulled apart. Anaphase is where things get fast; the sister chromatids are yanked to opposite sides of the cell by the spindle fibers. It’s honestly satisfying to watch under a microscope because of how perfectly symmetrical it looks.

Finally, there's telophase, where the new nuclear envelopes start to reform around the two sets of chromosomes. The cell basically starts to pinch in the middle, and once it fully splits—that's cytokinesis—you end up with two identical daughter cells. It’s a process that happens constantly in the body, and it's pretty crazy to think about how much is going on inside us at any given second.
