Ethics of Animal Cloning
"God blessed them and said to them, ‘Be fruitful and increase in number; fill the earth and subdue it. Rule over the fish of the sea and the birds of the air and over every living creature that moves on the ground. '" (NIV) Ten years ago Dolly, the first cloned mammal was born. She was a sheep cloned by scientists at the Roslin Institute in Scotland. (Oak Ridge) Since then there has been a swarm of controversy over cloning in general. (Caplan) Even as the technology and use of cloning advances, major ethical questions are raised. To answer these questions it is important to understand the cloning process and how it actually works. There are actually three different types of cloning, DNA Cloning, Reproductive Cloning, and Embryo Cloning. DNA cloning is just what it sounds like, cloning individual strands of DNA so they can be observed for study. This process has been around since the 1970 's. Since DNA strands are so small it is difficult to study them in small quantities. This process combines the DNA of the gene of interest with a bacterial plasmid that replicates the DNA. This process has been used extensively by the Human Genome Project but cannot be used to clone an entire specimen. (Oak Ridge) The second type of cloning, reproductive cloning, is where it gets interesting. This is the process used to clone Dolly. The process used in reproductive cloning is called "somatic cell nuclear transfer" (SCNT). In this process, scientists transfer genetic material from the nucleus of a donor cell from the animal to be cloned. This material is transferred into an egg whose nucleus has been removed. This new egg must be treated with chemicals or electric current to stimulate cell division. The embryo is then transferred to the uterus of a female host animal that carries it till birth. (Oak Ridge) As a side note, the researchers at Roslin named their sheep Dolly after Dolly Parton since she is quite well endowed and the donor cell used in the

    Reproductive Cloning- Reproductive cloning is a type of cloning which is performed for the purpose of creating a duplicate copy of another organism. It is accomplished using a process called somatic cell nuclear transfer. In 1996, Scottish researchers announced that they had successfully cloned the first mammal, a sheep that came to be known as Dolly. Numerous other mammals have been cloned since then, and cloning has become a contentious ethical and scientific issue in some parts of the world.…

    The Evaluation of Five Websites about Cloning Based on Their Credibility and Support by Peer-Reviewed Articles

    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.…

    What Is the Future of Humans If We Utilise All Aspects of Available Biotechnology?

    Cloning is the creation of an organism that is the exact genetic copy of another. There are multiple ways that cloning can be achieved through biotechnology. Artificial embryo twinning is the more basic version of cloning. It mimics the natural occurrence of twins as a zygote divides into a two celled embryo but this process takes place in a Petri-dish instead of the mother’s body. The resulting embryos are then placed in a surrogate mother where they are developed. The process that ‘cloning’ generally refers to is scientifically known as somatic cell nuclear transfer. In this procedure the DNA of a cell of an adult animal (the donor) is extracted from body cells and then reinserted into the egg of another animal of the same species. The egg, with its nucleus removed will replicate the DNA of the donor cells and continue to act like a freshly…

    Pros And Cons Of Artificial Cloning

    What is cloning? Cloning, a process in which genetically identical copies of a biological entity are produced. The copy is referred to as a clone because it has the same makeup as the original thing it was cloned from. Cloning can happen naturally through asexual reproduction where a one parent cell splits itself into two identical daughter cells. In humans cloning can happen naturally when a fertilized egg splits making two embryos with almost identical genetic makeup, although they do not look genetically identical to either parent. Artificial cloning in animals, or reproductive cloning, is what is erroneous since it can damage the original or the clone permanently. There are other forms of artificial cloning such as gene cloning and therapeutic…

    Human Cloning Pros And Cons Essay

    Human Cloning is the creation of a genetically identical copy of an existing, or previously existing, human being or growing cloned tissue from that individual (Cloning Fact Sheet). Scientists remove the nucleus, which contains the genetic material, from an egg. The genetic material from an adult somatic cell is removed and placed in the egg. It now has a complete set of genes. The egg is placed in a petri dish to allow it to develop into an embryo, which is placed into a surrogate mother to continue to grow and develop into a baby (Genetic Science Learning Center). This technique is called nuclear transfer or nuclear transplantation because they transfer the nucleus from one cell to another (Kilner). Therapeutic cloning is a technique of human…

    Over the years, science and technology have expanded to make it possible to create identical creatures. While new cloning technology is a great advancement, it raises a plethora of moral and ethical questions. Cloning may bring about new ways to find cures for babies, according to Philip M. Boffey, but cloning also “could usher in a new eugenics”. The problems produced from the prospect of cloning greatly outweigh the benefits.…

    Is Therapeutic Cloning Worth the Risk

    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.…

    Synthesis Essay on Cloning

    Introduction: Cloning hit the mainstream as a scientific debate when scientists cloned a lamb named Dolly in 1996. Cloning is a process that results in an identical genetic copy of a biological product such as cells, tissues, genes or entire entities. After scientists took cloning beyond the genetic engineering of simple DNA to actual mammals, the controversy grew to new heights. Cloning happens naturally. Plants and bacteria often use asexual reproduction, which tends to produce an exact genetic copy. Twins are another example of natural cloning. Scientists use artificial cloning for use with genes, reproduction and therapy. "Gene cloning produces copies of genes or segments of DNA," according to the National Human Genome Research Institute. "Reproductive cloning produces copies of whole animals. Therapeutic cloning produces embryonic stem cells for experiments aimed at creating tissues to replace injured or diseased tissues." Many argue that cloning can be beneficial in fields such as medicine, agriculture, and science. Others claims that cloning has a direct impact that challenges or runs counter to the moral or religious values of millions of people.…

    This process can either add or delete specific genomes of farm animals. A key point to remember is that cloning is achieved when the oocyte maintains its normal functions and instead of using sperm and egg genomes to replicate, the oocyte is inserted into the donor’s somatic cell nucleus.[9] The oocyte will react on the somatic cell nucleus, the same way it would on sperm cells.*…

    Satire On Cloning

    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…

    Therapeutic Cloning

    Scientists eventually cloned a sheep after many failed attempts. The sheep was named Dolly and was born on the 277th try. "Reproductive cloning is a very inefficient technique and most cloned animal embryos cannot develop into healthy individuals. For instance, Dolly was the only clone to be born live out of a total of 277 cloned embryos. This very low efficiency, combined with safety concerns, presents a serious obstacle to the application of reproductive cloning ("Cloning Fact Sheet.")." This could prove to be a wasteful as the embryos won't get a chance to develop into anything. Cloning could seem that way but there is no guarantee the embryos will be able to develop to begin with at all. Scientists using stem cell research or actual cloning of humans may be able to find a way to stop the loss of…

    Examples Of Foolishness In Shakespeare

    After reading the Shakespeare plays we were assigned this semester, one thing in particular caught my interest. It was the turnabout in the tetralogy; the turn from foolishness to wisdom and being changed by the choices made. The choices made become catalysts. The protagonist is broken down into base components and re-forged into a new being. Even the antagonists are changed. The only character that doesn’t seem to be affected is the Fool, who is an amalgam of both foolishness and wisdom. Shakespeare used the interaction and transition between the foolishness and wisdom of the kings to form the crux of these plays for the…

    Should Cloning Be Banned

    The subject of human cloning is a very controversial topic. The cloning of Dolly the sheep in 1997 by scientist Ian Wilmut generated a very unexpected reaction around the world. However these reactions were not all positive. Cloning refers to the development of offspring that are identical to their parents genetically. While it is referred to as an unnatural process, it can occur quite often in nature. Identical twins, for example, are clones. However, human cloning is very new and very complex. In this essay I will examine both sides of the argument into the banning of cloning starting with reasons why cloning should not be banned.…
