what does mitosis do

Mitosis is the process by which a single cell divides into two identical daughter cells. It plays a crucial role in cell growth, development, and repair. Mitosis ensures that each daughter cell receives an exact copy of the parent cell's DNA. This process is important for the growth and maintenance of multicellular organisms, as well as for the replacement of damaged or old cells. Additionally, mitosis is involved in asexual reproduction, enabling organisms to reproduce without the need for fertilization.
