What is Mitosis and the Phases?

What is mitosis? This is the technical word for the nuclear division of a cell. When this core of this cell divides it results in two identical sets of chromosomes. This is followed by cytokinesis, and the results are two separate cells called daughter cells. The phases of mitosis are prophase, metaphase, anaphase and telophase. What is mitosis, it is cell structure that splits to become two chromosomes, and has four stages. After which they have for the most part equal shares of that components of that cell. This happens only in eukaryotic cells, and it is varied with different species.

Learn about What is Mitosis and the Phases?

The first phase is called prophase. This is where the chromosomes that are typically spread out in the nucleus start to condense and forma a tight ball. Then the molecules of DNA of the chromosomes begin to interact with proteins and enzymes that help with replicating the genes. In genetic material, the nucleus is called chromatin and is a loosely bundled coil. The genetic duplication having already been done now has two sister chromatids. The chromosomes are visible with a high magnification light microscope. The centrosomes are close to the nucleus they consist of a pair of centrioles. Near the end, of this stage the element that encloses the cytoskeleton and nucleus will disappear. The cytoskeleton will be transformed into a spindle apparatus and works to pull the duplicated chromosomes apart in the anaphase.

Know About Steps of Mitosis

The mitosis phase two is called the metaphase, and this comes from the Greek meaning “after.” The centrosomes will pull the chromosomes through the centromeres toward the opposite ends of the cell. In this stage of mitosis, the chromosomes of the divided cell will line up, and the spindle framework will coordinate them. They are positioned symmetrically on the metaphase plate at the center of the original cell. The alignment is even and is caused by the pulling powers generated by the kinetochores on opposite sides.

Phase three is called the anaphase. There are two things that happen in this phase first the proteins that have bound the sister chromatids are cleaved. The spindle framework will pull these chromatids apart separating the chromosomes. They will develop into nuclei that are two daughter cells that are totally identical, as well as identical to the parent cells. This is sometimes in two stages called early and late anaphase. The early is defined as separation of sister chromatids. The late phase is the elongation of the microtubules and when the chromosomes are pulled apart further. The end of this stage is when they identical copies have succeeded in separating.

The final phase is called telophase which means the “end.” This is the opposite of the prophase. What is mitosis in this stage? When the chromosomes begin to move to the spindle pole they will uncoil and spread out. This spindle was made of the cytoskeleton and is deconstructed. The membrane is formed around the chromosomes, and the mitosis is complete, but the division of the cell is not.
