1 cell division is important
Mitosis is important as a form of reproduction in single-celled organisms, like the amoeba. Mitosis regulates cell growth, development, and repair in multicellular organisms.
2 growth, development, repair
The process of mitosis generates new cells that are genetically identical to each other. Mitosis helps organisms grow in size and repair damaged tissue. ... Some organisms can use mitosis to reproduce asexually. The offspring of asexual reproduction are genetically identical to each other and to their parent.
3 DNA is tightly packed up to fit in the nucleus of every cell. As shown in the animation, a DNA molecule wraps around histone proteins to form tight loops called nucleosomes. These nucleosomes coil and stack together to form fibers called chromatin
4 metaphase, anaphase, telophase
Interphase is technically not part of mitosis, but rather encompasses stages G1, S, and G2 of the cell cycle. The cell is preparing for mitosis.
5 During interphase, the cell copies its DNA in preparation for mitosis. Interphase is the 'daily living' or metabolic phase of the cell, in which the cell obtains nutrients and metabolizes them, grows, reads its DNA, and conducts other "normal" cell functions. This phase was formerly called the resting phase.
6 Mitosis allows for cells to produce identical copies of themselves, which means the genetic material is duplicated from parent to daughter cells. Mitosis produces two daughter cells from one parent cell. ... Each daughter cell is haploid, because it has half the number of chromosomes as the original parent cell.
