asb100 Posted June 4, 2010 Share Posted June 4, 2010 hey all!!!! i'm new here and am totally clueless about mitosis and meiosis...i'm beginner in genetics and so have no idea about the basic terms in this field:-(.... can someone plzz help me grasp this topic??? *asb* Link to comment Share on other sites More sharing options...
jimmydasaint Posted June 4, 2010 Share Posted June 4, 2010 What you need is a good animation with explanation and also to beat into your own head that meiosis only occurs to make gametes (sex cells - sperm and egg cells). Mitosis and here Meiosis and here also meiosis Good luck mate. jimmy 1 Link to comment Share on other sites More sharing options...
your-angel Posted June 4, 2010 Share Posted June 4, 2010 Hey, Mitosis is basically this: the process in which a sell divides into two, creating two genetically identical cells via the processes of prophase, metaphase, anaphase, telaphase and cytokineses. Meiosis however, form gametes or sex cells (egg and sperm). Instead of having two identical cells, you have four genetically identical cells. Again, the phases are prophase, metaphase, anaphase, telaphase/ cytokineses. The only other difference between mitosis and meiosis is the fact that meiosis has additional steps. Prophase II, Metaphase II, anaphase II, and telephase/ cytokineses II. Hope that helps!! Link to comment Share on other sites More sharing options...
CharonY Posted June 4, 2010 Share Posted June 4, 2010 That is actually not correct. Read the links of Jimmydasaint. The result of meiosis are not genetically identical cells. As already mentioned, it is important to note the differences in genetic material from body (somatic) cells and sex cells (gametes). Link to comment Share on other sites More sharing options...
your-angel Posted June 5, 2010 Share Posted June 5, 2010 WOW!!! I can't believe I missed that!! Thank you for pointing that out. Yes, Meiosis does not produce genetically identical cells. My bad!! Link to comment Share on other sites More sharing options...
Mr Skeptic Posted June 5, 2010 Share Posted June 5, 2010 It's actually the entire point of meiosis, to produce genetically diverse cells. They are all similar in that they have one set of genes each. If you had an entirely monozygotic cell, the results of meiosis would be identical (and this is the point of "hybrid" cultivars). Link to comment Share on other sites More sharing options...
asb100 Posted June 5, 2010 Author Share Posted June 5, 2010 Hey guys, thanks for helping me out...am still trying to get it and Jimmy, ( may i call u that?) those animations helped a lot!!!! Link to comment Share on other sites More sharing options...
Genecks Posted June 5, 2010 Share Posted June 5, 2010 Try breaking it down to a mnemonic. IPMAT Interphase Prophase Metaphase Anaphase Telophase These days, I've seen so many diagrams, drawings, things through microscopes, etc.. that I just know the basics of the process. It's burned into my memory. Even if I couldn't remember the terms, I'd know the basics of the process. But try building yourself a ground and working up. I think understanding and memorizing the term "IPMAT" for cellular mitosis is a good starting ground. 1 Link to comment Share on other sites More sharing options...
