Dolly the Sheep Essay

The Most Amazing Sheep! A major scientific achievement was done at the Roslin Institute because the cloning of a sheep was successful. The female sheep cloned was the first ever mammal to be cloned with an adult somatic cell, using nuclear transfer and it was named Dolly [1]. She was cloned by Ian Wilmut, Keith Cambell, and some colleagues. She was born on the fifth of July in 1996 and she lived until she was the age of 6. She has been called “The Worlds Most Famous Sheep” by BBC news [1]. Overall Dolly was a clone or a biological twin of her mother and she had a pretty unique life. The way Dolly was created is that Wilmut and his colleagues transplanted a nucleus from a mammary gland cell of a Finn Dorsett sheep into the enucleated egg of a Scottish blackface ewe. The nucleus-egg combination was stimulated with electricity to fuse the two and to stimulate cell division. The new cell divided and was placed in the uterus of a blackface ewe to develop. Dolly was born months later. This process is called Nuclear Transfer. This strategy that they used took them 276 attempts before the outcome could come out right [2]. Overall these are the steps that took place to create Dolly. The reason why they created Dolly is because the researchers at the Roslin Institute wanted to get new ways to produce medicine and get a better understanding of development and genetics. Dolly was produced as a part of a research at the institute to produce medicine in milk of farm animals. Researchers have now managed to transfer human genes that produce useful proteins into sheep and cows, so that they can produce, for instance, the blood clotting agent factor IX to treat haemophilia or alpha-1-antitrypsin to treat cystic fibrosis and other lung conditions [5]. These are the reasons why we created Dolly. Dolly started her life in a test tube and then ended up as a biological twin of her mother due to Nuclear Transfer.

    Ever since the birth of the first cloned sheep, named Dolly, the dream of human cloning has existed (Van Dijck, 1999). Cloning a mammal is described as the manipulation of an animal or human cell in order to create an identical copy of that animal’s or human’s nucleic DNA (Andrews, 1997). Though the dream of a human clone also comes with a lot of controversy regarding ethics and morals. Embryotic stem cell research, which could lead to a renewable source of human tissue, cells and eventually entire organs (Bowring, 2004), is highly controversial due to the necessity of placing a cloned embryo into a woman’s body in order to achieve that research. Politicians differentiate between therapeutic cloning and reproductive cloning as they refer to the second as “implanting a cloned embryo in a woman's womb” (Bowring, 2004), as for the embryo itself the research is not very therapeutic. Furthermore cloning by transfer of nuclei is not very effective yet as only 1% of manipulated sheep eggs reach adulthood and the number is even lower for other animals (Solter, 2000). The question whether human cloning will ever be possible and ethical remains to be answered but it seems certain that extra research in embryotic stem cells will improve techniques and success rates, which eventually brings the realization of a human clone closer one step at a time.…

    It is stated in the article “What is the Future of Animal Biotechnology?” by Alison L. Van Eenennaam that the “cloning procedure is currently inefficient, with only 1% to 3% of the nucleated egg cells developing into live offsprings” (Van Eenennaam). This statistic helps the audience infer that the cloning procedure must be very expensive. With such a low percentage of success, the audience can also infer that many embryos may’ve been wasted each time. In additional example is stated in “Dolly’s Death Resurrects Debate on Cloning Ethics” by Rosie Mestel: “to get Dolly, it took 277 tries” (Mestel).…

    The hybrid cell is then stimulated to divide by an electric shock, and when it develops into a blastocyst it is implanted in a surrogate mother.[8] Dolly was the first clone produced from a cell taken from an adult mammal. The production of Dolly showed that genes in the nucleus of such a mature differentiated somatic cell are still capable of reverting back to an embryonic totipotent state, creating a cell that can then go on to develop into any part of an animal.[9] Dolly's existence was announced to the public on 22 February 1997.[1] It gained much attention in the media. A commercial with Scottish scientists playing with sheep was aired on TV, and a special report in TIME Magazine featured Dolly the sheep.[10] Science featured Dolly as the breakthrough of the year. Even though Dolly was not the first animal to be cloned, she gained this attention in the media because she was the first to be cloned from an adult…

    (Aurelia et al. 3). In other words, cloning is a method of producing a child who has exactly the same genes or parent. (Aurelia et al. 3). The most common cloning technique is called Somatic cell nuclear transfer (SCNT) which involves putting the nucleus of a body cell into an egg from which the nucleus has been removed. This produces a clonal embryo, which is triggered to begin developing with chemicals or electricity. Placing this cloned embryo into the uterus of a female animal and bringing it to term creates a clone, with genes identical to those of the animal from which the original body cell was taken ("About Reproductive Cloning"). In Frankenstein, electricity is the tool which creates life and eventually creates “the monster”. Earlier medical experiments, including Galvanism, lead Victor Frankenstein to fantasize about the possibilities of creating life using the power of electricity and the body of a once living man. Mary Shelley seemed to be predicting into the future where, a modern day Victor Frankenstein would succeed in reanimating the lifeless or more inimical to our society: synthetically creating life. In fact, scientists have already cloned an animal. The first cloned mammal, named Dolly the sheep, died at the age of 6 years. The death of the first cloned mammal was followed by a lively debate related issues / ethical aspects of cloning, some of which continue the debate today. Only 1% of animal cloning made so far have had a positive result, but most of them have suffered serious disorders. The conclusion of experts is that the current level of technology, human cloning is very dangerous (Aurelia et al. 1) Many scientists even believe that reproductive cloning can never be made…

    Until the cloning of Dolly, the development of DNA and gene technology was sluggish. After the birth of Dolly, a new way of looking at genetics was found, raising the possibilities of human cloning. Human cloning, on the other hand, had been thought of as a pipe dream or a work of fiction until Scottish scientist Dr. Ian Wilnot successfully cloned an adult sheep Dolly in 1997. The birth of Dolly represents a considerable scientific and technological breakthrough in the field of cloning because it proved that cloning of animals from adult cells was possible. Dolly also is the most significant milestone in the observation of DNA and genetics and greatly facilitated every aspect of biochemistry. However, the rapid development of human cloning has become a most controversial topic for debating the question of whether cloning should be legal or not.…

    However, scientists still have still a lot to learn in the field of cloning. The first mammal to be cloned was Dolly the sheep in the year of 1996 on July 5th. Geneticists have already learned how to clone an animal and different cross-breeds of two organisms like the human-pig. They can also remove DNA strands and clone them to study the genetic makeup of the organism. The use of stem cells is that they can use the stem cells in experimenting different diseases to produce a new medication or more effective medication. Over the years, geneticists have accomplished composing stem cells and generating the duplicate of the same animal for…

    Cloning is the process of creating copies of DNA, cells, or organisms, in other words, it is the “creation of an organism that is an exact copy of another” (What is Cloning?). An early embryo cell is separated in a petri dish and injected into a surrogate mother. Through cloning, scientists are able to make an exact genetic copy of a living organism. The clone and the original are identical in every way. Clones are able to function and interact with other living things, just as the original is able to. After news of cloning Dolly the Sheep in 1997, cloning has been a controversial topic.…

Throughout her short story, Bishop talks about Gwendolyn’s beauty and fragility as a child with diabetes who was consistently on the verge of death until she finally passes at the end of the story. After her death, and at the very beginning of the story, Bishop depicts her encounter with a doll she was also fascinated with that belonged to her Aunt Mary. At the end of the story, she concludes, with the help of her cousin Billy, that “the doll’s real name, all this time, was Gwendolyn” (Prose, 61).…
