Definition of Mitosis



Mitosis is a biological phenomenon in which the cell divides into two daughter cells. The number of chromosomes in the daughter cells remain the same as the parent cell. The daughter cells are genetically identical to the parent cell as no reshuffling of chromatids takes place in mitosis. Mitosis occurs in almost all organisms except viruses. Mitosis makes somatic cells which are involved in executing all the functions of a body in contrast to meiosis which gives rise to germ cells involved in the process of reproduction.

 


There are four phases in mitosis. The prophase is a much shorter phase. The chromosomes align themselves along the equator and form equatorial plate in metaphase. During anaphase, the chromosomes get separated and form sister chromatids and the cell divides into two in telophase.
