Cloning of Animals
On Sunday, February 23, 1997, Scottish researchers broke one of nature's
greatest laws by cloning a lamb from a single cell of an adult ewe. This
breakthrough opens the door to the possibility for the cloning of other mammals
including humans.
This remarkable achievement is being looked at as a great advancement in
animal agriculture. But this achievement could lead to ethical questions of
standard.
Researchers lead by Ian Wilmut of the Roslin Institute in Midlothian,
Scotland, showed that a fully differentiated cell from the mammary tissue of an
ewe could be manipulated in such a way as to produce a genetically identical
copy of the animal that the DNA was acquired.
Scientist long believed that once a cell became differentiated, that
most of its approximately 100,000 genes shut off. Only a few genes remained
active to allow the cell to perform its specific function of life. All efforts
to reactivate the shut-off genes have failed. English researchers have came the
closest 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 before
their success, but the task was perfected and accomplished. Now this
accomplishment 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 to
death, something happens to break the
