Mitosis, the process of cell division, occurs to ensure growth and repair in multicellular organisms. Mitosis starts with one parent cell and results in two identical daughter cells. Mitosis perpetually generates new cells until the organism dies, according to Dr. Stephen M. Wolniak.
Mitosis is essential in the survival of multicellular organisms. In these organisms, mitosis occurs immediately after genesis. Cells continue to duplicate until the organism is fully developed. An adult human, for example, is made up of trillions of cells. Some of these cells become specialized and perform unique functions in the body. Cells that make up tissue, bones and organs all work together to help organisms function properly. With the exception of specialty cells, like brain cells, cells that die are constantly replaced by new ones.
Mitosis takes the genetic information of a parent cell and replicates it in the form of two identical daughter cells. This process occurs in four stages. During Prophase, chromosomes condense in the form of a tight coil as the nuclear membrane breaks down. During Metaphase, the replicated chromosomes move toward the middle of the cell, ensuring there is an equal amount of genetic material on each side. During Anaphase, the chromatids begin to pull apart toward the poles of the cell. During Telophase, the cell splits apart and the daughter cells are officially formed.
