What about meiosis? We'll teach you - it will be like hypnosis Mitosis starts off with prophase And once we're done you'll be in a daze First, chromosomes join and organize The nuclear membrane begins to hide The spindle apparatus soon appears Then it quickly attaches to centromeres In metaphase chromosomes line up at the equator Daughter cells will come later The chromosomes have been duplicat'd One spindle from each chromatid In anaphase centromeres will separate The chromatids will pull apart, just you wait For chromosomes that means twice as many What traits could they have? They could have any Chromosomes begin to retreat Two cells are about to secrete In telophase chromosomes go to the poles They are ready to fulfill their roles The nuclear membrane begins to reform The nucleoli are back, that's the norm Chromosomes begin to fade Two identical daughter cells will be made Chromosomes in telophase would be six*** That's more than the process has ever seen But these chromosomes are chromatids That's because of the centromeres, which we got rid Finally comes cytokinesis Mitosis will finally cease Cytoplasm quickly divide. The cleavage furrow pushes it to both sides And so the cell has finally split For mitosis, that's it Mitosis produces two diploids Meiosis produces two haploids They are different, that's ...

  • MEIOSISHIGHQUAL.mov Introduction: Different types of cells have different methods of reproduction. In a***ual reproduction, cells go through a process called mitosis. In this process, the replicated cells are genetically identical to parent cells, having the same DNA and number of chromosomes. Meiosis is a two-stage form of cell division which promotes genetic variation. In meiosis, daughter cells have half the number of chromosomes. These haploid cells, created by a mother and a father, combine in ***ual reproduction to form a diploid organism that can, in turn grow and reproduce. __ The process in which the cell divides in as follows: Interphase: Chromosomes replicate in the nucleus, but remained uncondensed. Each replicated chromosomes consists of two identical sister chromatids. The centrosome replicates, forming two centrosomes. Prophase I: -Chromosomes condense and appear -Homologous chromosomes (those with similar size, shape, and genetic information) loosely pair up. -A homologous pair could consist of, for example, a chromosome from the father and from the mother. -Two homologous pairs bound together and consisting of four sister chromatids are called tetrads. -In synapsis, a protein structure forms between the homologues, holding them tightly together. Often times, this causes a small breakage of the chromosomes. When the cell puts it back together parts of DNA from one chromosome are transferred to the other. This is called crossing over. -Chiasmata are the criss-crossed regions ...
  • What's The Difference Between Mitosis and Meiosis? A scientific spoof on the classic by Dr. Dre and Xzibit. What's the difference between mitosis and meiosis? What's the difference between mitosis and meiosis? Lets explain each, first we got mitosis The cell starts off in interphase, where it's kickin' with the homies The cell grows and grows, till its ready to split from them hoes With all its new chromosomes, its ready to goes Next is prophase, the chromatids pair at the centromere The mitotic spindle forms outside the nuclear envelope here. The centrosomes move to opposite poles. That's where they stays. The chromosomes on the plate we call it metaphase (yeah). Comin is Anaphase, microtubules pull back at the kinetochore Separate the chromosomes; make 'em look like they're tore. Last is telophase, the new nucleolus and envelope formed With the help of cytokinesis, two daughter cells are borned. Break at the cleavage furrow, the cell's pinched in two If ya didn't know it before, we aim to give ya a clue. What's the difference between mitosis and meiosis? Meiosis does the gametes, while somatics from mitosis Meiosis I has the unique chromosome pairing of a tetrad Crossing over at chiasmata, that's synapsis, its really rad. Meiosis is next, looks a lot like the first one If it didn't have two phases, it might be mitosis' son. Starts off the same, interphase begins Chromosomes duplicate, rollin in the nuclear envelope like rims Now hear it gets different, we hit prophase uno Homologous chromosomes pair, makin a tetrad sumo ...

  • Chiasmata Chiasmata takes us on a strange and beautiful journey through time, space and the portals of memory. In explaining his title, House remarks: "'Chi' is the Greek letter X, while a chiasma is an intersection or crossing. In the field of genetics, 'chiasmata' are the connection points where DNA strands exchange information; this exchange is the basis for the growth of a complex living organism. In this same spirit of exchange, the word chiasmata evokes other words such as chaos, stigmata, Laius (the ill-fated father of Oedipus), charisma, asthma, Mother and matter."

  • Cell Division Project: Mitosis and Meiosis AP Biology project by Shanshan Chen, Alex Yu, and Terry Mitchell I apologize in advance for the bad sound quality. acapella Lyrics: Let's Learn 'bout cell divi-sion Mitosis, the process by which your somatic cells are divided. 3 phases. G1, S and G2 make up interphase. Interphase makes up 90 percent of the cycle of cell division The cell grows and copies it's chromosomes to prepare. In prophase, chromatin fibers are coiled and become visible. Spindle fibers begin to form, along with sister chromatids. The nuclear envelope dissolves in prometaphase along with Kinetochores being attached to microtubules move the chromosomes which then line up in metaphase along the metaphase plate. Centrosomes begin to pull the chromatids apart in Anaphase. Each Chromatid then becomes a chromosome in it's own right. The cell lengthens and each end of the cell has equal DNA now. Two daughter nuclei begin to form in the cell's Telophase. The chromosomes then become less condensed to repeat Mitosis. Cytokinesis also occurs, the division of the cytoplasm and organelles. The cleavage furrow pinches the cell in two, making two identical daughter cells. Meiosis Section: Meiosis, the process by which *** cells called gametes are produced. Like Mitosis, but division occurs two times to make 4 daughter cells. The daughter cells are haploid, and have half the DNA of the parent cell. Prophase 1 homologous chromosomes group together. Tetrads allow for genetic variation to occur. Crossing over occurs at ...
  • Chiasmata - Breakout The Bodybags Chiasmata
  • Biology: Meiosis: Prophase I 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 "crosses over," or is exchanged. This exchange of homologous genetic information will be very important in further study of 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 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, evolution of life on earth, and plant systems and homeostasis.

The difference between haploid and diploid cells and the three major eukaryotic life cycles are then described. The program goes on to a detailed description of all the stages of Meiosis I and II including prophase I and II, metaphase I and II, anaphase I and II, and telophase I and II. In the process students are introduced to phenomena such as crossing over and provided an explanation of how meiosis creates genetic variability in a species.
