![]() ![]() The nuclear envelope starts to disintegrate, mitotic spindle begins to assemble, and centriole pairs move toward opposite poles of the cell. ![]() A centromere connects each chromatid to its copy, making the linked pairs look like X’s. Mitosis begins in prophase, where the chromosome condenses into chromatids. The two daughter cells will each have the same genetic code. Then the cell membrane can split the cytoplasm and organelles (termed cytokinesis). The events of mitosis describe the processes of splitting and moving nuclear DNA to opposite ends of the parent cell, where the nuclear membranes will reform. The DNA needs to be free from the nucleus so it can evenly distribute to two daughter cells. Remember that the DNA is in the nucleus, which is surrounded by the nuclear membrane. By observing the chromosome, one can identify the mitotic process. The stages of mitosis occur in sequence with specific events in each one. ![]() Mitosis steps consist of prophase, metaphase, anaphase, and telophase the cell undergoes nucleus division and split into two identical daughter cells. ![]()
