Cell Division, Meiosis Meiosis is the type of cell division by which germ cells (eggs and sperm) are produced. Meiosis involves a reduction in the amount of genetic material. Meiosis comprises two successive nuclear divisions with only one round of DNA replication. Cell Division,...

www.mindbites.com In this lesson, mitosis and meiosis are compared in terms of DNA replication, the number of divisions, the presence of synapsis, the number of daughter cells, and the numbers of chromosomes in the products and function. From a similarity standpoint (between meiosis and mitosis), in both: DNA is replicated and the process consists of phases (prophase, metaphase, anaphase, telophase). On the flip side, Meiosis and Mitosis differ along the following dimensions: number of divisions (1 for mitosis and 2 for meiosis), synapsis is only a characteristic of meiosis (in prophase I), the number of daughter cells produced varies (4 non-identical haploid cells in meiosis and 2 identical cells in mitosis), the number of chromosomes in resulting cells varies (2N in mitosis to match the original parent cell and only N in meiosis as the resulting cells are haploid), and the function/objective of the processes vary (somatic cells are produced via mitosis and gametes are produced by meiosis).Taught by Professor George Wolfe, this lesson was selected from a broader, comprehensive course, Biology. This course and others are available from Thinkwell, Inc. The full course can be found at www.thinkwell.com The full course covers evolution, ecology, inorganic and organic chemistry, cell biology, respiration, molecular genetics, photosynthesis, biotechnology, cell reproduction, Mendelian genetics and mutation, population genetics and mutation, animal systems and homeostasis <b>...</b> Biology Mitosis...

The Gregor Mendel LP. Hi, Meiosis
www.mindbites.com In this lesson, Professor Wolfe starts to discuss the individual phases of meiosis, which are very similar to the phases of mitosis. Meiosis, however, requires two cell divisions because of the creation of haploid cells from the sister chromatids. Ninety percent of meiosis occurs in the first phase, known as Prophase I. In this phase, two very important events occur. The first is the formation of a tetrad through the process of synapsis. Synapsis is the pairing of homologous chromosomes, which form the tetrad structure. These tetrads create areas called chiasmata (chiasma, if singular), where homologous genetic material ..." onmouseout="mouseOutImage(this, '4', 'FFFFFF')" onmouseover="mousOverImage(this,'-ubeAsBWODY',1, '4','FFCC00')" /> Biology: Meiosis:...
