Mitosis is a type of cell division where one cell divides into two identical daughter cells. This process is essential for growth, development, and repair of tissues in organisms.Here's a breakdown of the main steps in mitosis: * Prophase: The chromosomes condense and become visible. The nuclear envelope breaks down, and the spindle fibers begin to form. * Metaphase: The chromosomes line up at the equator of the cell, attached to the spindle fibers. * Anaphase: The sister chromatids of each chromosome are pulled apart and move to opposite poles of the cell. * Telophase: The chromosomes at the poles begin to decondense, and new nuclear envelopes form around them. The spindle fibers disappear. * Cytokinesis: The cell divides into two daughter cells, each with a complete set of chromosomes.In essence, mitosis ensures that each new cell receives a perfect copy of the original cell's genetic material.
