Mitosis is the step in the cell cycle that the newly duplicated DNA is separated, and two new cells are formed. This process is important in single-celled eukaryotes, as it is the process of asexual reproduction. In multi-celled eukaryotes, mitosis is how a single zygote can become an entire organism. Mitosis has several distinct stages, or phases,...
Development
In multi-celled organisms, life always starts as a single cell, formed from two gametes. This zygote carries all the DNA necessary to create a fully functioning organism, but not near enough cells. The purpose of mitosis is to produce more cells. After the first round of mitosis, there are only two cells. These cells both undergo mitosis, and there are 4 cells. Pretty soon, a small, hollow ball of cells is formed, called the blastula. This ball folds in on itself as more and more cells are cr...
Replacing Damaged Tissues
The second important function of mitosis is that of repair. When an organism gets injured, its cells are damaged. This can be a physical injury like a cut, or damage from environmental sources like the sun. Either way, the damaged cells need replaced. Nearby cells, not sensing their neighbor cells, turn on the pathways that start the process of mitosis. Eventually the multiplying new cells reach each other, and the damage area is covered with new cells. Some organism are able to regenerate en...
Though technically not part of mitosis, Interphase begins and ends mitosis. Interphase is the part of the cell cycle in which the cell grows and duplicates the DNA. After an identical set of DNA is synthesized, the cell enters Mitosis.
Cell Cycle– In eukaryotes, the cycle consists of Interphase and Mitosis, with some cells going into a non-diving third state.Cytoplasm– The fluid surrounding the DNA in cells.Microtubules– Small structures in the cytoplasm of cells made from proteins, which allow the cell to move various organelles and chromosomes.Binary Fission– The process of cell division in prokaryote, which differs do to the lack of organelles and associated membranes.1. A cell duplicates its DNA, divides into two cells, then divides into two cells again. Effectively, the cell reduces its DNA in half. Did this cell go through mitosis? A. Yes, but only once. B. Yes C.No 2. During mitosis, the chromosomes have condensed, lined up on the metaphase plate, and the chromatids are being separated by an enzyme? Which ph...
Mitosis is the process of cell division that produces two identical daughter cells from one parent cell. Learn about the stages of mitosis, the functions of mitosis in development and repair, and the difference between mitosis and meiosis.
Chromosomes carry genetic information in a molecule called DNA. A type of cell division called mitosis ensures that when a cell divides each new cell produced has the same genetic information.
- Prophase. Prophase is the first step of mitosis. This is when the genetic fibers within the cell’s nucleus, known as chromatin, begin to condense and become tightly compacted together.
- Metaphase. Metaphase is the phase of mitosis that follows prophase and prometaphase and precedes anaphase. Metaphase begins once all the kinetochore microtubules get attached to the sister chromatids’ centromeres during prometaphase.
- Anaphase. The third phase of mitosis, following metaphase and preceding telophase, is anaphase. Since the sister chromatids began attaching to centrosomes on opposite ends of the cell in metaphase, they’re prepped and ready to start separating and forming genetically-identical daughter chromosomes during anaphase.
- Telophase. Telophase is the last phase of mitosis. Telophase is when the newly separated daughter chromosomes get their own individual nuclear membranes and identical sets of chromosomes.
Learn how cells undergo mitosis, the process of nuclear division, and the stages of cell cycle. Explore the history, mechanisms, and regulation of mitosis with diagrams and examples.
May 11, 2006 · Mitosis is the cell division process that produces two identical daughter cells with the same genetic material. Learn about the stages of mitosis, from interphase to cytokinesis, and how it differs from meiosis.
