Phases of mitosis\n \nThe cell cycle.The mitotic phase is a relatively short action-packed period of the cell cycle. It alternates with the much longer interphase, where the cell prepares itself for division. Interphase is divided into three phases, G1 (first gap), S (synthesis), and G2 (second gap). During all three phases, the cell grows by producing proteins and cytoplasmic organelles. However, chromosomes are replicated only during the S phase. Thus, a cell grows (G1), continues to grow as it duplicates its chromosomes (S), grows more and prepares for mitosis (G2), and divides (M).\n\nMitosis is a continual and dynamic process. For purposes of description, however, mitosis is conventionally broken down into five subphases: prophase, prometaphase, metaphase, anaphase, and telophase.\n\n[edit]\nProphase\n \nProphase: The two round objects above the nucleus are the centrosomes. Note the condensed chromatin.Main article: Prophase \nNormally, the genetic material in the nucleus is in a loosely bundled coil called chromatin. At the onset of prophase, chromatin condenses together into a highly ordered structure called a chromosome. Since the genetic material has already been duplicated earlier in S phase, the chromosomes have two sister chromatids, bound together at the centromere by the protein cohesin. Chromosomes are visible at high magnification through a light microscope.\n\nJust outside the nucleus are two centrosomes. Each centrosome, which was replicated earlier independent of mitosis, acts as a coordinating center for the cell's microtubules. The two centrosomes sprout microtubules (which may be thought of as cellular ropes or poles) by polymerizing free-floating tubulin protein. By repulsive interaction of these microtubules with each other, the centrosomes push themselves to opposite ends of the cell (although new research has shown that there might be a mechanism inside the centromeres that also grab the microtubules and pull the chromatids apart). The network of microtubules is the beginning of the mitotic spindle.\n\nSome centrosomes contain a pair of centrioles that may help organize microtubule assembly, but they are not essential to formation of the mitotic spindle. Plant cells that lack centrioles have no trouble undergoing mitosis.\n\n[edit]\nPrometaphase\n \nPrometaphase: The nuclear membrane has degraded, and microtubules have invaded the nuclear space. These microtubules can attach to kinetochores or they can interact with opposing microtubules.Main article: Prometaphase \nThe nuclear envelope dissolves and microtubules invade the nuclear space. This is called open mitosis, and it occurs in most multicellular organisms. Some protists, such as algae, undergo a variation called closed mitosis where the microtubules are able to penetrate an intact nuclear envelope.\n\nEach chromosome forms two kinetochores at the centromere, one attached at each chromatid. A kinetochore is a complex protein structure that is analogous to a ring for the microtubule hook; it is the point where microtubules attach themselves to the chromosome. Although the kinetochore is not fully understood, it is known that it contains a molecular motor. When a microtubule connects with the kinetochore, the motor activates, using energy from ATP to "crawl" up the tube toward the originating centrosome. The kinetochore provides the pulling force necessary to later separate the chromosome's two chromatids.\n\nWhen the spindle grows to sufficient length, kinetochore microtubules begin searching for kinetochores to attach to. A number of nonkinetochore microtubules find and interact with corresponding nonkinetochore microtubules from the opposite centrosome to form the mitotic spindle.CXV\n\nPrometaphase is sometimes considered part of prophase.\n\n[edit]\nMetaphase\n \nMetaphase: The chromosomes have aligned at the metaphase plate.Main article: Metaphase \nAs microtubules find and attach to kinetochores in prometaphase, the centro

the correct order:\n\n1) Chromosomes copy themselves (interphase).\n2) Chromosome copies fasten together as the nuclear... (prophase).\n3) Chromosomes line up in the center of the cell (metaphase).\n4) Chromosome copies separate (anaphase & telophase).\n5) Cell splits (cytokinesis).\n\nThis is correct. Disregard the former answers.

Mitosis is the splitting of one cell into two daughter cells.  The phases can be summed up into the acronym IPMAT.\n\nI interphase - has a G1 or growth one phase where cellular growth and DNA translation occur.  S or Synthesis phase where DNA is translated assembled and condensed.  G2 or growth two phase where cytoplasmic growth occurs.\n\nP prophase - where DNA starts condensing into chromosomes and centromeres polarise the cell forming spindal fibers.\n\nM metaphase - is when DNA is fully condenced and chromosomes are in equatorial allignment\n\nA anaphase - karyokenesis is complete, new nuclear membranes form and cytokenesis begins furrowing.\n\nT telephase - clevage furrowing completes to initiate a new G1 phase.

mitosis:the process in cell division by which the nucleus divides, typically consisting of four stages: prophase, metaphase, anaphase and telophase.\n\nmeiosis: (genetics) cell division that produces reproductive cells in sexually reproducing organisms; the nucleus divides into four nuclei each containing half the chromosome number (leading to gametes in animals and spores in plants) \n\nosmosis:Transmission of fluids from one cell into another; foundation of metabolism, led by the concentration of salt within a cell. Water can penetrate cell membranes, and strives to, where the concentration of salt is highest, in order to equalize the salt concentration in the body.

Cytokinesis is part of mitosis where the cell membrane divides

The cells undergo a process known as mitosis. This is when the chromosomes will duplicate themselves and then split into two cells. Hormones often tell cells when to begin mitosis. Your skin grows in 3 layers. The cells towards the inside will multiply and push older skin cells towards the 2nd, and 3rd layer until they die and fall off. This means that your skin in constantly renewing itself.

Mitosis\n\nThe beginning of mitosis is called prophase. In early prophase, the centrosomes move toward opposite poles of the cell, organizing the spindle microtubules between them. The sister chromatids become visible in the nucleus as they condense. \n\nIn late prophase, the nuclear membrane breaks down and some of the spindle microtubules attach to the sister chromatids. The microtubules pull the chromatid pairs to the midline of the cell, or metaphase plate.\n\n•••\n\nThe chromatids remain lined up between the poles of the cell during metaphase.\n\n•••\n\nAnaphase begins when the pairs of sister chromatids separate. The separated chromatids are now called chromosomes, and move toward the poles of the cell.\n\n•••\n\nThe chromosomes arrive at the poles in telophase, and new nuclear membranes form around them.\n\n•••\n\nDivision of the cytoplasmic components is called cytokinesis. \n\nIn animal cells, cytokinesis occurs when a ring of actin and myosin filaments constricts the plasma membrane at the equator. Eventually, the parent cell is divided into two cells.\n\nAnimal Cytokinesis Movie (500K)\n\n\n\nIn plant cells, a number of small vesicles fuse at the metaphase plate to form the cell plate. Over time, the cell plate reaches across the cell and joins with the plasma membrane.\n\n•••\n\nThe process of mitosis and cytokinesis creates two separate cells, each with an identical set of chromosomes. After cytokinesis, the daughter cells will enter interphase.

ur question should be under biology but still, mitosis is the process of when the cells split to create 4 indentical cells during mitosis, one copy of the dna is distributed into each of the tow daughter cells mitosis id divided into 4 interphases: prophase, metaphase, anaphase, and telophase. in prophase, the chromatin in the nucleus condenses to form chorosomes. structures celled spindle fibers form a bridge between the ends of the cell. the nuclear membrane breaks down. in metaphase, the chromosomes line up across the center of the cell. each chromosome attaches to a spindle fiber at its centromere, which still holds the chromatids together. in anaphase, the centromeres split. the two chromatids separate. one chromatid moves along the spindle fiber to one end of the cell. the other chromatid moves to the opposite end. the cell becomes stretched out as the opposite ends pull apart. in telophase, the chromosomes begin to stretch out and lose their rodlike appearance. this occurs in the two regions at the ends of the cell. a new nuclear membrane forms around each region of chromosomes. o yeah and btw mitosis is on stage of the cell cycle there are like 2 before it and 1 after it

There are 3 stages of interphase. Gap 1 (G1) that is the first growth phase. Synthesis phase (S) phase which is the phase where the chromosomes replicate. Gap 2 (G2) is the second growth phase where the cell prepares for division.
