Cloning is Not What it Used to Be :: Cloning Argumentative Persuasive Argument

Cloning is Not What it use to Be On Sunday, February 23, 1997, Scottish researchers broke one of naturesgreatest laws by copy a lamb from a single cell of an with child(p) ewe. Thisbreakthrough opens the door to the possibility for the cloning of other mammalsincluding humans. This remarkable movement is being looked at as a great advancement inanimal agriculture. But this achievement could lead to ethical 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 way as to produce a genetically identicalcopy of the animal that the deoxyribonucleic acid was acquired. Scientist long believed that once a cell became differentiated, thatmost of its approximately 100,000 genes leave out off. Only a few genes remainedactive to allow the cell to come its specific function of life. All effortsto reactivate the shut-off genes entertain fail ed. English researchers have came theclosest by teasing frog body cells to develop into tadpoles. The tadpoles,however, neer matured into frogs. The Scottish researchers have failed many times with sheep cells beforetheir success, provided the task was perfected 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 bringing them close todeath, something happens to break the chemical substance locks (barriers) that confirm mostof the genes inactive. The mammary cell is inserted into an unfertilized sheep bombard cell that has already had all of its own genetic material 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 gen esinto startle over again, as if they were brought 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 organisation prohibits government funds beingspent on human cloning research, and ethicists castigate it, nevertheless, humancloning could be achieved, Neal First said. First is a prof of animalbiotechnology and reproductive biology at the University of Wisconsin. Overall, there is no apparent reason to clone humans. A duplicate bodydoes non mean a duplicated mind.
