Cell Cycle
Cell reproduction is the leading cause of growth and developement in our bodies. This reproduction is caused by the cell cycle, which is defined as the life of a cell from its origin in the division of its parent cell until its own division into two. Genetic continuity, cytokinesis regulation, and tumor formation are three parts of the cell cycle. Mitosis and Meiosis are main events of the cell cycle that assure reproduction of cells. The process of meiosis affirms genetic continuity from a parent to a child, while mitosis affirms a genetic clone from one cell to the next. Meiosis takes place in order for sexual reproduction to occur, while mitosis regulates growth and repair among cells and tissue. Both processes incude: interphase, prophase, metaphase, anaphase, and telophase as their main steps during divisions. During interphase, the cell prepares itself for division. In this stage, the chromosomes and centromeres are replicated. Chromosomes are still undistinguishable due to loosly packed chromatin fibers. The nucleus is well-defined and bounded by a nuclear envelope, conta
If a problem occurs in the cell cycle, and a malfunction in cell growth results, malignant tumors, also known as cancer may form. Metaphase, the next phase in cell division, involves the lining up of chromosomes at the metaphase plate of the cell. To conclude, the cell cycle is important for regulation of production of new, healthy cells in the body. If and when these cells stop dividing, they may do so at random points in the cycle or between phases. The cells usually have an irregular number of chromosomes, and if a tumor spreads through circulatory passage ways, it can cause harm or even death to the entire organism. Since they include a cell wall, the boundries around the cell must be harder and more rigid. A potential problem may occur during transformation, which is the process that converts a normal cell to a cancerous one. This cell plate enlarges until its surrounding membrane fuses with the plasma membrane along the perimeter of the cell. In animal cells, the first sign of this process is the cleavage furrow, a shallow groove near the surface of the metaphase plate. Cytokinesis, which takes place during telophase, occurs in both plant and animal cells. The cycle goes through 5 main steps in order to reproduce: interphase, prophase, metaphase, anaphase, and telophase. When prophase occurs, changes take place in the nucleus and cytoplasm. The cell is now prepared for anaphase, the following step, which is where the chromatid detach from one another and travel to opposite poles of the cell. The difference between mitosis and meiosis is that mitosis occurs in one stage, forming to diploid cells, whereas meiosis occurs in two stages forming 4 haploid cells. One example may be that cancer cells have no need for growth factors in their culture medium.
