	Embryo cloning, adult DNA cloning and therapeutic cloning
		For cloning's advocates, this is an opportunity to remake mankind in an image of health, prosperity, and nobility; it is the ultimate expression of man's unlimited potential.
		The cloned organ would be based on the recipient’s genetic material and would not require the use of debilitating immunosuppressive therapies.
		The goal of therapeutic cloning is to produce a healthy copy of a sick person's tissue or organ for transplant.

	Cloning - Wikipedia, the free encyclopedia
		Frequently, the term cloning is misleadingly used to refer to the identification of the chromosomal location of a gene associated with a particular phenotype of interest.
		Thus, nuclear transfer clones from different maternal lineages are not clones in the strictest sense because the mitochondrial genome is not the same as that of the nucleus donor cell from which it was produced.

	NIMR :: Mill Hill Essays 1997 :: Cloning
		Clones traverse the cinema screen as crowds of dehumanised humans destined for monotonous drudgery, as invincible armies of lookalikes from outer space, as replicas of living megalomaniacs and, in the ultimate fantasy, as the resurrected dead - troupes of little Hitlers and herds of rampaging dinosaurs.
		Lower vertebrates had been cloned in the early 1960s when it was shown that a nucleus taken from an adult frog cell transplanted to a frog egg whose own nucleus had been destroyed was able to direct the development of that egg into a swimming tadpole.
		Cloning is as important to the production of fine wine, the supply of rubber and the fruit harvest as it is to the variety of an English country garden.

	Category:Cloning - Wikipedia, the free encyclopedia
		Cloning is the process of creating an identical copy of an original.
		A clone in the biological sense, therefore, is a multi-cellular organism that is genetically identical to another living organism.
		Sometimes this can refer to "natural" clones made either when an organism reproduces asexually or when two genetically identical individuals are produced by accident (as with identical twins), but in common parlance the clone is an identical copy by some conscious design.

	Cloning Webliography
		A major breakthrough in animal cloning occurred in 1997 when Ian Wilmut and his group at the Roslin Institute in Scotland cloned a sheep (Dolly) using genetic material from a non-embryonic cell, an adult mammary gland cell (3).
		Cloning from adult cells means that it is possible to be more certain ahead of time what the cloned animal will be like.
		Cloning of organisms, like many new technologies, is controversial because it is difficult to predict what good or bad could come from it.

		Cloned children might also suffer from disruption to a phenomenon called imprinting, in which genes are normally activated differently depending on whether they come from the mother or the father.
		Abstract: The announcement of a cloned sheep from the DNA in a single udder cell of a 6-year-old ewe has ignited a debate on ethical implications of cloning and sparked the imaginations of researchers regarding the scientific implications and potential of cloning.
		Cloning mammals by splitting embryos in half is not new, but cloning mammals from cells that are not embryonic is. To create Dolly, the Roslin team took cells from the udder of a Finn Dorset ewe.

	CBC News Indepth: GENETICS AND REPRODUCTION
		Human cloning is perhaps the most controversial reproductive technology, raising fears in people's minds of armies of clones or exact copies of people long dead.
		Cloning experts were skeptical about the claim, saying cloning a human is technically demanding and the group lacks the skills to do it.
		Some are against cloning for the same reason they're against abortion and euthanasia – because all human life is valuable and destroying embryos is equal to murder.

	Cloning Fact Sheet
		To "clone a gene," a DNA fragment containing the gene of interest is isolated from chromosomal DNA using restriction enzymes and then united with a plasmid that has been cut with the same restriction enzymes.
		Once the cloned embryo reaches a suitable stage, it is transferred to the uterus of a female host where it continues to develop until birth.
		Cloning extinct animals presents a much greater challenge to scientists because the egg and the surrogate needed to create the cloned embryo would be of a species different from the clone.

	Primer on Ethics and Human Cloning by Glenn McGee, Ph.D.
		Proponents of cloning suggested it might serve as a new, unusual but perhaps efficacious treatment for infertility, enabling those unable to pass genes to future generations to do so in a way that is at least analogous to the familial linkage of twins.
		How a clone is to be defined, or rather how difficult is the task of finding a way of understanding human cloning in terms from traditional language and contemporary institutions of science and parenting, has proven to be a most formidable challenge.
		While it is tempting to describe cloning as either a radical new form of parenting or as twinning, either analysis fails to take account of the need for new ways to integrate the problem of cloning into social institutions before it becomes an accepted form of reproductive medicine.

	Cloning - cells, plants & animals
		A clone produces cells that not only have the same chromosomes, but which turn on the same genes, turn off the same genes, and therefore look identical, act the same, and do the same things.
		Cancer cells are natural clones and were the first human cells isolated and grown in laboratories.
		Twins are nature's clones, and we know they do not act alike or have the same personality at all.

	cloning
		The first reproducible cloning of a mammal from adult cells, which has successfully yielded three generations and more than 50 identical cloned mice, is reported in the July 23 issue of the international science journal Nature by an international team of scientists, lead by Ryuzo Yanagimachi, of the University of Hawaii.
		Whereas gene cloning and the manipulation and transfer of genetic material within and across species has been a scientific reality for more than two decades, cloning complete organisms, and in particular mammals, has long been the a topic of science fiction thrillers, shrouded in futuristic mystique.
		The clone is virtually genetically identical to the adult sheep that donated the nuclear material, with the one exception being the of small amounts of mitochondrial DNA that remain in the cytoplasm of the egg.

		Reproductive cloning uses the cloning procedure to produce a clonal embryo which is implanted in a woman's womb with intent to create a fully formed living child--a clone-as shown in diagram 3 above..
		Therapeutic cloning uses the cloning procedure to produce a clonal embryo, but instead of being implanted in a womb and brought to term it is used to generate stem cells, as shown in diagram 4 above.
		Others oppose therapeutic cloning as well as reproductive cloning, either because they are opposed to the destruction of embryos as a matter of principle, or because they feel the acceptance of therapeutic cloning will set us on a slippery slope to the acceptance of reproductive cloning and human genetic manipulation.
