What is mitosis?

How are mitosis and meiosis different?

Why is mitosis important to organisms?

mitosis, a process of cell duplication, or replica, during which one cell gives ascend to two genetically identical daughter cells. Purely applied, the full term mitosis is in use to identify the duplication and distribution of chromosomes, the structures that stockpile the genetic information.

A brief treatment of mitosis follows. For a full treatment, see growth: In cells; cell: Mitosis and cytokinesis.

Prior to the onset of mitosis, the chromosomes have replicated and the proteins that will form the mitotic spindle wealthy person been synthesized. Mitosis begins at prophase with the deepening and coiling of the chromosomes. The nucleolus, a rounded structure, shrinks and disappears. The end of prophase is scarred past the beginning of the organization of a aggroup of fibres to form a spindle and the disintegration of the nuclear membrane.

The chromosomes, each of which is a double structure consisting of duplicate chromatids, wrinkle up along the midline of the cell at metaphase. In anaphase each chromatid pair separates into two identical chromosomes that are pulled to other ends of the cell by the spindle fibres. During telophase, the chromosomes begin to decondense, the spindle breaks belt down, and the nuclear membranes and nucleoli re-form. The cytoplasm of the mother cadre divides to take form two daughter cells, each containing the same number and kind of chromosomes as the father cell. The stage, or phase, after the mop up of mitosis is titled interphase.

Mitosis is dead intrinsic to biography because information technology provides new cells for growth and for replacement of worn-out cells. Mitosis may take minutes or hours, depending upon the kind of cells and species of organisms. It is influenced by clip of day, temperature, and chemicals.
