Mitosis

/maɪˈtoʊsɪs/ noun

Definition

Mitosis is the process by which a cell divides into two new cells that are genetically identical to the original. It is how your body grows, heals wounds, and replaces old cells.

Etymology

From Greek “mitos,” meaning “thread,” and “-osis,” indicating a process or condition. The name refers to the threadlike appearance of chromosomes during cell division under a microscope.

Kelly Says

The name mitosis literally comes from the ‘threads’ scientists saw when they first watched cells divide. Those threads are chromosomes, and every time your skin heals or you grow, billions of these tiny thread-shows are happening silently inside you.
