Mitosis And Meiosis Essay. Words9 Pages. Describe the processes of mitosis and meiosis in details and their functions. Introduction. Cell division does not stop with the formation of the mature organism but continues in certain tissues throughout life. It is because cell cannot grow any larger Mar 23, · Meiosis, on the other hand, comprises of two divisions taking place separately and the chromosomes are reduced by half. The key difference is, whereas mitosis produces two diploid cells, the two cells produced in meiosis are haploid in nature, containing one of each pair of chromosomes. These cells are, usually, involved in syngamy Feb 11, · Mitosis and meiosis are both forms of cell division, however, their processes are not identical. Mitosis happens in somatic cells (cells that are not gametes), and it produces two genetically identical daughter cells. Mitosis happens to replace dead or damaged cells or during growth

Mitosis and meiosis essay and meiosis are both forms of cell division, however, their processes are not identical. Mitosis happens in somatic cells cells that are not gametesand it produces two genetically identical daughter cells.
Mitosis happens to replace dead or damaged cells or during growth. Mitosis consists of 4 phases: prophase, metaphase, anaphase, and telophase.
DNA replication happens during S phase which is before the mitotic phase. During prophase, the chromatin condense into chromosomes, and the mitotic spindle forms textbook, During metaphase, the chromosomes line up along the middle of the cell, known as the metaphase plate. During anaphase, the chromatid pairs separate, and each half of the pair is called a chromosome.
During telophase, mitosis and meiosis essay, the last stage of mitosis, mitosis and meiosis essay identical sets of chromosomes are at opposite poles of the cell, the chromosomes revert back to chromatin, and a nuclear envelope reforms around each group of chromatin. The division of the cytoplasm after nuclear division is called cytokinesis textbook, Meiosis, in contrast, occurs in gametes sex cellsproduces four genetically different daughter cells, mitosis and meiosis essay, and involves two divisions of genetic material.
Meiosis is broken up into into two parts: meiosis I and meiosis II which both consist of four parts. Meiosis I occurs first after DNA replication and consists of prophase I, metaphase I, anaphase I, and telophase I. Prophase I, much like prophase in mitosis, is when the chromosomes shorten and the mitotic spindle forms. However, unlike prophase in mitosis, the two genetically identical sister chromatids pair off, and crossing over occurs between non sister chromatids.
Crossing over is the very important reason that no two people have the same DNA. Metaphase I is very similar to metaphase in mitosis because the homologous pairs of chromosomes line up along the metaphase plate. In anaphase I, the homologous pairs of chromosomes are separated and pulled to opposite sides of the cell leaving the paired chromatids still together textbook, Meiosis I results in two genetically different haploid cells after telophase I and cytokinesis which are similar to telophase and cytokinesis of mitosis.
Meiosis II consists of prophase II, metaphase II, anaphase II, and telophase II. Prophase II is similar to prophase in mitosis, and no crossing over occurs during prophase II. Metaphase II is when the sister chromatids line up along the metaphase plate. During anaphase II, the sister chromatids separate and move to opposite poles mitosis and meiosis essay the cell. The final step of meiosis is telophase II and cytokinesis where the nuclear envelopes reform and four, mitosis and meiosis essay, genetically different haploid mitosis and meiosis essay are formed as a result of the original single diploid cell textbook, Remember: This is just a sample from a fellow student.
