Genetic therapy vs Genetic enhancement (P282) The woman with the spiky hair recognized him and yelled at him, ‘Leave playing God to God’” One of the most controversial discussions there has been in genetics, is whether the use of genetic therapy or genetic enhancement are moral permissible or not. On one side, there is the genetic therapy which uses genetic research to cure an illness. In the novel ‘Sister’ by Rosamund Lupton, there is a big example of this, since the sister of the protagonist,

of plants & animal cells are: * Mitochondria are where enzymes are, where aerobic respiration reactions take place. * Cytoplasm is a gel-like substance where anaerobic respiration takes place as some controlled enzyme reactions take place here. * Cell membrane is what controls what goes in and out of the cell as it acts like a barrier allowing water & gases to pass through easily. What does the bacteria cell consist of? * They have a simple cell structure of a circular

parent and results in identical cells. Scientifically speaking, one cell could be cloned, as well as organs, plants, even animals and perhaps humans. Just as varied, are the reasons to clone in the first place. The possibilities of cloning range from medical uses, personal uses, agricultural and livestock improvement to saving endangered species and more. The medical advantages cloning provides extend life, treat illnesses, and produce medications. Research into cell growth and genetics adds understanding
