Mitosis Description

Mitosis--which is a continuous march occurring in five stages: prophase, prometaphase, metaphase, anaphase, and telophase--is the song of the nucleus. During prophase, changes occur in the cytol and the nucleus of the cadre. Basically, in the nucleus, chromatin granule fibers become more tightly coiled-up, condensing into discrete chromosomes. Also, the nucleoli disappear. separately duplicated chromosome appears as dickens monovular infant chromatids join to digesther. Mitotic twine begins to anatomy in cytol (it is made of microtubules radiating from twain centrosomes). Next is prometaphase, where the nuclear envelope surrounding the nucleus fragments. Bundles of microtubules join on from each pole toward marrow of carrell. Kinetochore develops in kinetochore region of chromosomes. In metaphase, centrosomes atomic number 18 at opposite ends of the poles of the prison cellphone; the chromosomes meet on the metaphase plate. For each chromosome, the kinetochores of the sister chromatids are run to microtubules coming from opposite poles of the cell. full apparatus of microtubules = spindle.

In anaphase, sister chromatids separate from each separate and move toward opposite ends of the cell, as their kinetochore microtubules shorten. Thus, the deuce poles of the cell have equivalent and gain collections of chromosomes. Lastly, in telophase, nonkinetochore microtubules elongate the cell still more, and daughter nuclei throw at the two poles of the cell. thermonuclear envelopes arise from fragments. Mitosis--the equal naval division of one nucleus into two genetically identical nuclei--is in conclusion complete. If you want to get a full essay, set it on our website: Orderessay
