Strictly applied, the term mitosis is used to describe the duplication and distribution of chromosomesthe structures that carry the genetic information.
Mitosis is a process of cell duplication, in which one cell divides into two genetically identical daughter cells. Mitosis is the division of a cell into two daughter cells that are genetically identical to the parent cell. Meiosis is the division of a germ cell into four sex cells e. Mitosis is a means of asexual reproduction, whereas meiosis is necessary for sexual reproduction. Many single-celled organisms rely on mitosis as their primary means of asexual reproduction.
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 have been synthesized. Mitosis begins at prophase with the thickening and coiling of the chromosomes. The nucleolus, a rounded structure, shrinks and disappears. The end of prophase is marked by the beginning of the organization of a group 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, line up along the midline of the cell at metaphase. In anaphase each chromatid pair separates into two identical chromosomes that are pulled to opposite ends of the cell by the spindle fibres. During telophasethe chromosomes begin to decondense, the spindle breaks down, and the nuclear membranes and nucleoli re-form.
The cytoplasm of the mother cell divides to form two daughter cells, each containing the same number and kind of chromosomes as the mother cell.
The stage, or phase, after the completion of mitosis is called interphase. Mitosis is absolutely essential to life because it 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 time of day, temperature, and chemicals.

The increase in size and changes in shape of a developing organism depend on the increase in the number and size of cells that make up the individual. Increase in cell number occurs by a precise cellular reproductive mechanism called mitosis.

Meiosis involves the creation of cells that are not genetically identical where, as in mitosis, the cells are the same as the parent cell. Sample Question. S phase.

A type of cell division called mitosis ensures that when a cell divides each new cell produced has the same genetic information. DNA exists in a cell's nucleus within structures called chromosomes.
Each section of a chromosome that contains the code for the production of a particular protein is called a gene. Each chromosome is made from a single molecule of DNA, but when a cell is ready to divide, the DNA copies itself, then coils and condenses to form the chromosomes that we see in micrographs. Each human body cell contains 46 chromosomes. These can be arranged into 23 pairs. Each chromosome in a pair carries the same types of genes.
The 23rd pair are the sex chromosomes:. Cell division Chromosomes carry genetic information in a molecule called DNA.In Cell Division-Mitosis Song
The 23rd pair are the sex chromosomes: In females, the two chromosomes are identical in shape. There are two X chromosomes.
Females are referred to as XX. In males, one of the chromosomes is a different in shape. There is an X and also a Y chromosome. Males are referred to as XY.
