Mitosis

• Mitosis is the part of cell cycle that results in identical daughter nuclei that are also genetically identical to the original parent nucleus.
• Nuclear division also known karyokinesis is a continuous process but it is conveniently divided into four different stages
• prophase is marked condensation of chromosome to form visibly distinct chromosomes. The chromos made up two sister chromatids joined together at the centromere.
• Chromosome

  structures within the nucleus that are made up of DNA, the genetic material of an organisms
• metaphase, in this phase, chromosomes are aligned in a plane called metaphase plate, or the equatorial plane, midway between the two poles of the cell. The significant event occurred in metaphase stage is the alignment of chromosomes at the middle in plane called metaphase plate
• As prophase progresses, the chromosomes become shorter and thicker as result of intricate coiling. In the late, prophase, the nuclear membrane disintegrates, the nucleolus disappears and mitotic spindle forms. Look at the picture to appreciate the prophase stage.
• anaphase. In this stage, the centromeres divide and the two sister chromatids move toward the opposite poles of the spindle. The movement results from a pulling to the poles by spindle fibers that are attached to the centromeres.
• Telophase, starts when the chromosomes reach their spindle poles. The chromosomes complete uncoiling, the spindle fibers apparatus is dismantled, nucleolus reappears and nuclear envelope form around each chromosomes cluster.
• Telophase is completed when cytokinesis has taken place and two daughter cells are produced.
• Cytokinesis is a process of the division of the cytoplasm
• In animal's cell, cytokinesis starts with a cleavage furrow or indentation around the middle that eventually pinches in, dividing the cell into two while on the plant cell is the formation of cell plate.
