Mitosis and Growth – Basics and Principles

How it works

Mitosis is the process of nuclear division in eukaryotes, in which one cell gives rise to two genetically largely identical daughter cells. It consists of several phases: prophase, metaphase, anaphase and telophase; this is usually followed by cytokinesis. Mitosis serves growth, regeneration and, in some organisms, asexual reproduction. Before mitosis, the genetic material is duplicated in interphase; during mitosis, the chromosomes are distributed evenly to the daughter cells. Errors in distribution can lead to disorders or diseases. Mitosis must be distinguished from meiosis, which serves to form germ cells.

Note
In mitosis, one cell gives rise to two genetically largely identical daughter cells. The genetic material has previously been duplicated and is distributed evenly to both daughter cells during mitosis.

An example

What function does mitosis have in the human body?

Mitosis enables growth and the repair of tissues by producing new, genetically identical cells. (Mitosis ensures that cells for growth and healing are formed.)
