What is the difference between mitosis cytokinesis and cell division

A stem cell is a cell with the unique ability to develop into specialised cell types in the body. In the future they may be used to replace cells and tissues that have been damaged or lost due to disease. If you have any other comments or suggestions, please let us know at comment yourgenome.

In metaphase individual chromosomes pairs of chromatids line up along the equator. During anaphase the sister chromatids are separated to opposite poles.

During karyokinesis, cells undergo a series of steps to divide the duplicated chromosomes into two equal sets.

On the other hand, during cytokinesis, cells undergo a series of processes to divide the cell content into two equal halves. Mitosis is consists of five stages , prophase, prometaphase, metaphase, anaphase, and telophase. Each chromosome in a prophase cell consists of two sister chromatids attached to one centromere.

In this stage, chromosomes become more condensed and can be seen under a light microscope. At this stage, mitotic spindle consisting of microtubules and other proteins forms between the two pairs of centrioles as they drift to opposite poles of the cell.

However, this structure can not be seen in some plant cells. Prometaphase starts with degeneration of nuclear membrane. Some spindle fibers attach to the centromere regions of the chromosomes. Microtubules attach to the either sides of the sister chromatids, to kinetochores. Then the other end of these microtubules attaches to the centrosome of the opposite poles. In this phase, chromosomes are arranged along the center of the cell, metaphase plate as a single line.

After the metaphase connection between sister, chromatids break down, and chromatids move to the opposite direction from each other, i. Molecular motor proteins disassemble tubulin molecules in the spindle and generate force so that chromosomes are pulled towards the opposite poles from each other.

Once chromatids moved to the spindle poles, the chromatids are referred as chromosomes. Mitosis itself is the division of the nuclei into daughter nuclei. It includes five phases of its own. Prophase: Here, chromosomes become more condensed in the nucleus, and the nuclear membrane dissolves. The mitotic spindle forms from the centrioles, which have split and moved to opposite poles sides of the cell. This spindle is made of proteins in the form of microtubules. Prometaphase: In this step, the chromosomes migrate toward the center of the cell.

They are propelled by the mitotic spindle apparatus attached at the centromeres that joins sister chromatids. They begin to approach a line perpendicular to the direction they are moving, through their centromeres, called the metaphase plate. Metaphase: In this step, chromatids align precisely along the metaphase plate via their centromeres, with one sister chromatid on each side of the metaphase plate.
