Mitosis

__**//Mitosis and it's stages//** __

__What is Mitosis?__ Mitosis is the process in which a cell separates, creating two identical sets of the cell before. Mitosis only happens in eukaryotic cells. The steps of mitosis are Prophase, Anaphase, Metaphase, and Telophase. The step before mitosis is called Interphase.

__Interphase__

Interphase happens right before mitosis starts. Interphase is divided into three phases: The G1 phase, the S phase, and the G2 phase. The way the cell grows and keeps growing enough to start mitosis is by producing protein. In the G1 phase the cells starts growing, then in the S phase the cell keeps growing and the chromosomes are duplicated, then in G2 phase it finishes growing and starts preparing to start mitosis.

__ Prophase __

Prophase is the first step of Mitosis. In prophase, the chromatins starts to condense and the chromosomes become visible under the microscope. The nucleolus also disappears. The centrioles moves to opposite ends of the cell. Fibers from the centrosomes starts extending as seen in the picture above. Some of those fibers create spindles.

__ Metaphase __



Metaphase is the second step in Mitosis. In this phase the spindle fibers align the chromosomes in the middle of the cell. This line is usually called the metaphase plate.

__Anaphase__



Anaphase is the third phase in mitosis. In this phase, the chromatids go to the opposite ends of the cells and the cells starts breaking in half.

__ Telophase __

Telophase is the last phase in mitosis. In this phase you see a cell plate forming in the middle of the cell if it is a plant cell. But if it is a animal cell it just splits the cytoplasm to make to daughter cells. This process is known as cytokinesis. The nucleoli and the nuclear membranes starts to form again and the chromosomes uncoil to chromatin. Later on the two daughter cells start interphase, grow up and starts mitosis all over again.
