Description:
The primary result of mitosis is the transferring of the parent cell's genome into two daughter cells. These two cells are identical and do not differ in any way from the original parent cell. Mitosis occurs in our heart, liver, brain, skin, blood and more. Why is Mitosis so important?

Terms | Definitions |
|---|---|
 Interphase | Chromosomes are copied. Chromosomes appear as threadlike coils at the start, but each chromosome and its copy change to sister chromatids at the end of this phase. |
| Prophase | Mitosis begins as centrioles appear and begin to move to opposite ends of the cell. Spindle fibers form between the poles. |
| Metaphase | Chromatids attache to the spindle fibers. The chromosomes line up along the middle of the cell. |
| Anaphase | Chromatids separate and begin to move to opposite ends of the cell, pulled along by the spindle fibers |
| Telophase | Cell membrane moves inward to create two daughter cells - each with its own nucleus with identical chromosomes. |
| Cytokinesis | Two new nuclei form. Chromosomes appear as chromatin. Mitosis ends. |
| Centromere | The most condensed and constricted region of a chromosome, to which the spindle fiber is attached during mitosis. |
| Mitosis | Cell division in which the nucleus divides into two nuclei containing the same number of chromosomes with an end result of two identical cells. |
| Nucleus | a part of the cell containing DNA and RNA and responsible for growth and reproduction |
| Spindle Fibers | Special microtubules made of proteins which connect to centromeres and pull apart chromosomes. |
| Sexual Reproduction | A mode of reproduction involving the fusion of female gamete (egg) and male gamete (sperm), which forms a fertilized cell that potentially develops into genetically distinct offspring. |
| Meiosis | A type of cellular reproduction in which the number of chromosomes are reduced by half through the separation of homologous chromosomes in a diploid cell. The process that creates sex cells (eggs and sperm). |
