The video tutorial explains the process of mitosis, highlighting its distinction from cytokinesis. It covers the stages of interphase, where the cell grows and replicates its chromosomes, and the phases of mitosis: prophase, metaphase, anaphase, and telophase. The tutorial details the role of centrosomes, microtubules, and kinetochores in chromosome alignment and separation. It concludes with cytokinesis, where the cytoplasm divides, resulting in two identical cells.
