Cloning is Not What it Used to Be :: Cloning Argumentative Persuasive Argument
Cloning is Not What it Used to Be On Sunday, February 23, 1997, sparing researchers broke one of naturesgreatest laws by copy a lamb from a single cell of an adult ewe. Thisbreakthrough opens the door to the possibility for the cloning of other mammalsincluding humans. This remarkable achievement is being looked at as a great advancement inanimal agriculture. But this achievement could lead to honourable questions ofstandard. Researchers lead by Ian Wilmut of the Roslin Institute in Midlothian,Scotland, showed that a fully differentiated cell from the mammary tissue of anewe could be manipulated in such a look as to produce a genetically identicalcopy of the animal that the DNA was acquired. Scientist long believed that once a cell became differentiated, thatmost of its approximately 100,000 genes fill up off. Only a few genes remainedactive to allow the cell to perform its specific function of life. All effortsto reactivate the shut-off genes have failed. English researchers h ave came the imminent by teasing frog body cells to develop into tadpoles. The tadpoles,however, never matured into frogs. The Scottish researchers have failed many times with sheep cells beforetheir success, but the task was hone and accomplished. Now thisaccomplishment has made it possible for the cloning of almost any mammal,including humans. To the average person, exactly how the technique works is unclear.Scientist predicted that by making cells dormant and rescue them close todeath, something happens to break the chemical locks (barriers) that keep mostof the genes inactive. The mammary cell is inserted into an unfertilized sheepegg cell that has already had all of its own genetic significant removed. Byfusing the cells together tricks the egg into thinking that it has becomefertilized. After being fused together, researchers believe that the chemicalmachinery inside the egg cell goes to work to reprogram the mammary cell genesinto starting over again, as if they were broug ht together as sperm and egg.The cell divides, produces an embryo, fetus and a newborn that is identical tothe animal from which it was cloned. Although the United States administration prohibits government funds beingspent on human cloning research, and ethicists decry it, nevertheless, humancloning could be achieved, Neal First said. First is a professor of animalbiotechnology and reproductive biology at the University of Wisconsin. Overall, there is no apparent reason to clone humans. A duplicate bodydoes not believe a duplicated mind.
