Explore mitosis as a type of cell division focused on karyokinesis, with a step-by-step look at the stages—prophase, metaphase, anaphase, and telophase—and their biological significance.
During prophase, chromatin condenses into visible chromosomes, and spindle fibers begin to form.

During anaphase, the centromeres split, and sister chromatids are pulled to opposite poles by spindle fibers.
