  Dolly the sheep
When Dolly was cloned in 1996 from a cell taken from a 6 year old ewe, she became the centre of a controversy that still continues today.
Dolly was put down on February 14, 2003, due to complications from a lung infection.
It is arguable that Dolly is perhaps the perfect example of scientists focusing in on highly specialised areas, to such an extent that they are no longer able to see the wider picture, and for that matter, the implications of their endeavours.

 Good-bye to Dolly the cloned sheep.
Dolly's life was ended at the age of 6 (about half the life expectancy of her breed) when a veterinarian confirmed she had a progressive lung disease.
Dolly was cloned from the udder cell of a 6-year-old adult sheep.
Dolly did produce offspring, so if there was a genetic component to her early death the progeny will be studied to see if the detrimental effects are passed on.

The name "Dolly" came from a suggestion by the stockmen who helped with her birth, in honour of Dolly Parton, because it was a mammary cell that was cloned.
When Dolly was cloned in 1996 from a cell taken from a six-year-old ewe, she became the center of much controversy that still exists today.
Dolly was a Finn Dorset lamb, created from fully differentiated adult mammary cells using a technique called somatic cell nuclear transfer; her creation was described in a Nature publication in 1997.

 cooltech.iafrica.com | tech news Dolly the sheep is put down
Dolly the sheep, the first mammal to be successfully cloned from an adult cell, has been put down after she was found to have a lung disease, the Roslin Institute in Scotland's capital Edinburgh said on Friday.
Dolly's creator, Professor Ian Wilmut, told AFP it was "perhaps slightly young" for the six-year-old sheep to contract the illness, amid concerns that she had suffered premature ageing.
Dolly's birth in July 1996 from the breast cell of a six-year-old adult ewe made scientific history and her death at six years old had serious implications and poses deep concerns over the science of cloning.

 Guardian Unlimited | The Guardian | Dolly the sheep is put to sleep, aged only six
Dolly the sheep, the world's first animal to be cloned from an adult cell, has been put to sleep, it was announced yesterday.
Dolly was born on July 5 1996, from three mothers: one ewe to provide the DNA, another to provide the egg into which the DNA was injected, and a third to carry the resulting cloned embryo to term.
Dolly's genetic mother (the DNA was taken from an udder cell, and her name was a reference to Dolly Parton) was six when she was cloned.

 Happy Dolly
Dolly and two other cloned sheep have shorter telomeres -- the tiny strands of DNA at the end of chromosomes that scientists believe may hold the secrets to youth and aging.
In Dolly's case the shortening was compounded because she was derived from a cell from a middle-aged animal.
Dolly is unique, she has her own DNA set; she has her own character which is formed by both gene-gene interactions and gene-environment interactions.

LONDON (AP) — Dolly the cloned sheep was put to death Friday, after premature aging and disease marred her short existence and raised questions about the practicality of copying life.
The decision to end Dolly's life at age 6 — about half the life expectancy of her breed — was made because a veterinarian confirmed she had a progressive lung disease, according to the Roslin Institute, the Scottish lab where she was created and lived.
Ian Wilmut, the leader of the team that created Dolly, said it was unlikely her illness was attributable to being a clone.

The arthritis further fueled worry among some that this form of cloning may not be appropriate for mammals, and there is now a consensus both in- and outside scientific community that at this point the risk of unforeseen effects of cloning on the clone makes experiments in human reproductive cloning premature and unethical.
After the cloning was successfully demonstrated by Dolly's creators once, many other large mammals have been cloned, including horses and bulls.

Dolly, the cloned sheep, was born in Scotland on July 5, 1996 and raised the stakes of cloning, bringing the world closer to the possibility of human cloning.
Although Dolly is a clone, she is not a true genetic clone of one sheep, since she does not have precisely the same genetic makeup as the adult sheep she was cloned from.
This is because Dolly’s cells, from the adult udder’s sheep, are not the same as the egg, with which it was merged.

 Dolly, the famous cloned sheep!   (Site not responding. Last check: 2007-10-12)
Dolly, the famous cloned sheep represents the Holy Grail of human reproduction.
Dolly was made from a mammary (breast) cell and showed that not only could a mammary cell make more mammary cells, but that it could make an entire lamb.
When the DNA was taken out of the mammary cell and placed in an egg cell (ovum) from another sheep, apparently whatever is inside the egg cell caused the DNA to lose its differentiation and return to the germ cell state, capable of becoming anything, not just mammary tissue.

The fourth and final 'parent' of Dolly was her surrogate mother, who unlike many of the other sheep in these experiments, did not have to undergo a caesarian section.
Dolly is thus not so much a revelation of scientific truth as a construct of the society which produced her.
It seems so, because Dolly's genesis was funded by a grant from our government, a fact that came to public attention in the somewhat ironic circumstances of the announcement of its withdrawal shortly after the cloning story broke.

 Howstuffworks "Creating a Better Clone"
PPL Therapeutics, a Scotland-based biotechnology company involved in the creation of Dolly, has produced two sheep clones whose genes have been selectively modified.
To pinpoint the location on the sheep chromosome into which the new gene would be placed, researchers identified the flanking regions, like bookends, of the DNA that was to be replaced and the DNA to be introduced.
Next, using the method that resulted in Dolly, the altered fibroblast cells were fused with sheep eggs from which the nuclei had been removed.

These experiments at Roslin led to two sheep, Megan and Morag, cloned from a single embryo, and then to Dolly, cloned from a cell from the udder of a six-year-old Finn Dorset ewe.
The nucleus of the adult cell was substituted for the nucleus of another female's egg and brought to term in the womb of a third sheep.
Wilmut is a great ambassador, alongside Dolly, whom he once called the "friendly face of science", but years of hostile and ill-informed debate about cloning Saddam seem to have taken their toll.

The first sheep altered using the method may be born later this year, though it will be several years before scientists will have developed the means to alter many genes simultaneously, which will be necessary to boost growth or make leaner beef.
In earlier work, the Roslin team unveiled Megan and Morag, sheep that had been cloned by taking a cell from an early embryo, mass-producing it in the laboratory, and using these cells to "re-program" two emptied eggs.
In this case, the resulting lamb - Dolly - was genetically identical to the sheep from which the cell was taken.
