Question

How do humans use mitosis?

Answer 1

Mitosis:

Mitosis is the process through which a cell copies its chromosomes and then segregates them, resulting in two identical nuclei, ready for cell division.

Mitosis in humans:

• Growth and development

1. Mitosis is responsible for the development of the zygote into an adult.
2. Equal distribution of chromosomes to each daughter cell.
3. It is responsible for the growth and development of an individual.
4. It maintains the constant number of chromosomes in all body cells of an organism.

• Replacement and Regeneration of new cells

1. Mitosis is essential for the regeneration and replacement of worn-out and damaged tissues in living organisms.
2. Mitosis promotes the production of identical copies of cells, which contributes to the healing of wounds and the replacement of worn-out cells.
3. In multicellular organisms, however, the degree of regeneration and replacement varies.
