Mitosis Steps

In order to keep living organisms healthy cells have to go through many stages to replace damaged or worn out cells. One of the necessary steps is mitosis. Mitosis is the process of the body cell and nuclei dividing. This division is the cause of bodies growing and cells repairing. This division is a continuous process which there is four major steps; prophase, metaphase, anaphase, and telophase. Mitosis is comprised of prophase, metaphase, anaphase, and telophase. In prophase chromosomes compact and coil, each chromosomes consists of a pair of sisters. In this phase the nucleolus disappears and stops making ribosomes. The second stage is metaphase. This is a very brief stage and it's where all the chromosomes line up in the middle of the cell and each chromosomes attaches to a spindle fiber at its chromere. The …show more content…
A cancer cell will ignore the checkpoints that's regulating mitosis, cancer begins when a single normal cell is transformed from a regular cell to a cancer cell. This is often due to a change in function or a DNA mutation that occurs in one of the several genes that function to control growth. The first unusual feature is that cancer cells are frequently immortal. Normal cells can only divide about 50 times and then die, but cancer cells can go on dividing frequently, but they have supplied with nutrients. The second unusual feature is that cancer cells usually have unusual numbers of chromosomes or mutations in chromosomes unlike with normal cells have 46 chromosomes. The third unusual feature is that cancer cells have an abnormal cell surface, and rather than sticking to its neighboring cells, cancer cells tend to round up and break attachments to its neighbor cells allowing for metastasis. The last unusual feature is that cancer cells ignore the unusual density dependent inhibition of growth in cell culture increasing after contact with other cells are made,piling up until all nutrients are
