... . As defined in the text, a somatic cell is "any cell in the body except a germ cell," and contains the same entire set of DNA. Dolly's story is revolutionary, in that, before her birth, it was deemed unfeasible to make a somatic cell differentiate as if it were a fertilized egg. Dolly, conversely, changed that notion. She was created by taking a somatic cell from the udder of a white-faced sheep ... and depleting it of all nutrients so that it ceases to develop. It is then electrically fused with an egg taken from a black-faced sheep. The egg, having had its nucleus removed, is stripped...

... cloning. A scientist would take an ovum from a female donor, removing the nucleus and thus leaving an "empty" egg. From there, a single skin cell (somatic cell) would be removed from either, or both, parents and the nucleus from these somatic cells would then be inserted into the " ... This number could be largely reduced worldwide through the process of Therapeutic Cloning. Starting out quite similarly to adult DNA cloning, with a nucleus inserted into an empty egg. But rather than allowing the egg carry out the process of development into a child, it's growth would be stopped around the...

... started in 1997 by Rael, the leader of the Raelian movement who believes that extraterrestrials created human life on earth. They say that extraterrestrials used DNA and genetic engineering to create all life on earth. Until lately there wasn't a federal law against human cloning in the United States. Recently the ... process that was used to make Dolly. They will first remove the nucleus of an egg which makes an enucleated egg. A cell that contains DNA will be taken from the person to be cloned. Next, the egg and the cell will be fused together using electricity. This process creates an ...

... one or more cells from an embryo and encouraging the cell to develop into a separate embryo with the same DNA as the original (Robinson). In vitro fertilization is a form of cloning in which sperm and an egg cell are mixed together on a glass dish (Robinson). After the sperm and egg have united, the zygote (fertilized egg) can either be inserted into a female body to mature into ... 1997. On February 23, 1997 the press released information stating that the first successful cloning of a mammal using a cell from an adult sheep had occurred. "Dolly, a seven-month old sheep, was displayed t...

... . The cells turn off their active genes, and go into hibernation. An unfertilized egg is then taken out of an adult ewe, and the eggs nucleus, along with its DNA, is sucked out. Thus leaving an empty egg cell that still has the cellular machinery to produce an embryo. The empty egg and the culture of the starved cells are then placed next to each ... other. An electronic pulse causes the egg and cells to fuse together, and a second pulse is given to ... start the cell division. Six days later, the embryo is implanted in the uterus of another ewe. The result of this process is the birth ...

... for embryonic development (this included extraembryonic membranes and tissues, the embryo itself, and all postembryonic tissues and organs). In the first few hours after fertilization, the fertilized egg undergoes several cell divisions that produce identical totipotent cells. Because these cells are still totipotent, any one of these cells has the potential to develop into an entire human being. The totipotent cells ... match the patients DNA are needed to minimize the danger of rejection. A technique called Somatic Cell Nuclear Transfer is used to create compatible stem cells. Dolly ...

"These were the first people to clone an animal, the first to change the genetic structure of a cloned animal. Now they are the first ... cloning of dolly. Using somatic nuclear transfer, Wilmut and his team of researchers inserted the nucleus of an adult udder cell into a sheep egg cell whose nucleus had been removed. When the egg with the new nucleus begins to divide, Wilmut implanted the developing embryo into the uterus of another shee...

... transfer involves the use of two cells. The receiving cell is normally an unfertilised egg taken from an animal soon after ovulation. The donor cell is the one to be copied. A scientist removes the chromosomes, a chain-like substance that incorporates the cell's DNA, from the recipient egg cell. The donor cell is then combined with the recipient egg. Some fused cells start to develop like a normal ... embryo and produce progeny if implanted into the uterus of a surrogate mother'.

... by using Therapeutic cloning. This is the use of cloning for the sole purpose of healing or helping a patient. Scientists use stem cells to repair or re-grow any needed cell or organ. This would probably be the first step in trying to introduce cloning as a positive procedure. To fully make a decision on human cloning it is essential to understand how ... it is accomplished. First you have to have an unfertilized human egg and be impregnated with a cell that has the DNA from the human to be cloned. Then that egg has to be implanted into a surrogate mother and carried to term. The newbor...

The nucleus of the removed cell is removed, and transferred into an egg from which the DNA has been removed. It is then cultured, and implanted as an embryo into the womb of a surrogate ... . b.

... may follow this pattern. Cloning, in the future, could also be used to save endangered species. How? Well cloning allows people to turn any cell into an animal. Instead of injecting DNA into an egg, you can shoot DNA into cells in a petri dish. It can also be useful to increase the population of hard-to-breed animals. Cloning can also help us bring ... ...
