To Go the Star Wars Rout: Cloning

Cloning occurs when you copy a living creature. Two clones have the same genes, small structures with information in them that tells them what the body of a living thing should look like and how it should behave. You get the genes from your parents. Many people think that cloning is only done by scientists in laboratories, but, in fact, cloning also occurs in nature. Animals have billions of cells. The nucleus of such a cell has genetic information called DNA. All the nuclei of an animal have the same information. But each cell only uses a part of this information in order to work properly. The other part of the DNA is not active. But because a single cell holds all the DNA of an animal, scientists can make physical copies of an animal from only one cell. They transfer the nucleus of an animal’s cell into an egg cell of another animal. This egg cell has the same genetic information as that of the donor animal. The cell then grows into an embryo. Scientists must then activate the DNA that was not active in the parent cell. Otherwise a full organism would not develop. Clones do not behave in an identical way – this is because they live in different environments. Researchers have found out that identical twins that carry the same DNA are different because they grow up differently. Cloning animals started way back in the 1950s when the first frogs were reproduced. In 1996 British scientists cloned the first mammal, a sheep called Dolly. Since then the cloning of mice, cattle, cats and other mammals has been successful. Clones occur naturally in many cases, for example, when a mother gives birth to two…...

...Karren 1 Camille Karren Mrs. Robertson English 5A 12 December 2012 Human Therapeutic Cloning Should Be Permitted Human therapeutic cloning has the ability to greatly improve the quality of life. Cloning could be the answer to the end of your pain and suffering, but before you can understand it’s benefits, you have to know the process therapeutic cloning itself. Therapeutic cloning is a procedure in which cells, typically skin cells, are taken from a patient and inserted into a fertilized egg whose nucleus has been removed. Scientists then extract stem cells from the egg, and use those cells to grow tissue that are a perfect genetic match to the patient. It is a break-through in science and the key to curing many diseases including Parkinson's and Alzheimer's disease. Elizabeth Foley explains why human cloning should not be banned due to, “the primary objections to human cloning appear to be unfounded, based more on morality, theology, and fear than objective data.” The potential medical benefits of genetic engineering are far too great to let moral concerns about embryonic cell use get in the way of curing diseases. Human therapeutic cloning should not be banned from society because countless lives can be saved through transplantations and genetic research. Therapeutic cloning is the cloning of human tissues for research and transplant, and shows much promise in organ transplantation. Much needed organs grown from stem cells from the patient’s own genetic...

...Jeremy A. Belvin-Reed 6-27-2012 Human Cloning: Unproven, Unsafe Human Cloning is the most controversial subject in biotechnology today. It can be defined as the act of creating a new individual (reproductive) or organism (therapeutic) from the single cell of a parent subject. In reproductive cloning (human cloning) a parent subject is expected to act as a surrogate mother. Making the clone involves using the parent’s empty egg (nucleus and genetic code removed) combined with the nucleus of their own skin cells to create 1 embryo which is now a copy of them. Each time a procedure is formed a life hangs in the balance. This life is treated as property to be experimented on, without consent. People are being sold fantasies with ideas such as clones replacing us and another you. Whether you know it or not, resources for these procedures are costly to you. And so far, non-one is being held responsible. reports that “even if a mere 100 eggs were taken from ten donors, the cost of simply paying the donors could easily reach $50.000.” In hindsight, you are actually paying, out of your tax dollars, $1000 an egg. 12-14 of these eggs are transplanted into one surrogate. If you have 3 patients, the cost of the procedure skyrockets to $42,000 more of your tax dollars.“That means costs to treat one patient (human) could......

...Argumentative Essay 21st March, 2013 Cloning The twenty first century has brought in many extraordinary breakthroughs one of which happens to be cloning. Cloning can be defined as the process of creating a cell, tissue line or even a complete organism from a single cell (Jane Maienshchein, 2001). Cloning was a mere dream that people in the past used to have and wish upon, where cloning has been seen to be an impossible desire that no man can achieve. However, nowadays technology has reached levels that people thought would never reach and spread into so many branches and depths that now it has become safe to say that nothing is really impossible. Breaking the impossibility, many questions are being asked and many arguments are taking place around human cloning. Cloning has been considered to not just human beings but to animals as well. When the sheep dolly was cloned, the issue of cloning became something familiar to read about in the news. Many headlines have helped the public consider about taking part in this serious issue that is human cloning. Questions start to rise regarding the possibility of human cloning, and of course technology, they are questions that never stop. What has started out as thoughts and ideas about human cloning written down on papers, are now ideas that are being turned in to live experiments preformed in the labs. Away from the different views of the religious organizations and people’s thoughts and disagreement, cloning can be considered a......

...Cloning march 13, 2009 Justin Palmer Stem cell basics: introduction The possibility of human cloning, raised when Scottish scientists at Roslin Institute created the much-celebrated sheep Dolly aroused worldwide interest and concern because of its scientific and ethical conclusions. The feat, cited by science magazine as the breakthrough of 1997, also created uncertainty over the meaning of "cloning" - a term traditionally used by scientists to describe different processes for duplicating biological material. The most common form of cloning is called reproductive cloning. There are different types of cloning and cloning technologies that can be used for other purposes besides producing the genetic twin of another organism. A basic understanding of the three different types of cloning are : (1) recombinant DNA technology or DNA cloning, (2) reproductive cloning, and (3) therapeutic cloning. I learned a lot from this article something that I found was really interesting is this process called "somatic cell nuclear transfer". This process is where the scientist transfer genetic material from the nucleus of a donor adult cell to an egg whose nucleus, and then its genetic material, has been removed. The reconstructed egg containing the DNA from a donor cell must be treated with chemicals or electric current in order to stimulate cell division then placed inside the mother and continues with a normal birth. This changes my opinion on......

...2010 Cloning Human, animal, and plant cloning is one of the most controversial subjects in modern science. There are many good arguments in favor of cloning, as well as many against it. In my opinion, plant and animal cloning could be very efficient to society by way of creating more food, but I also view it as unethical. In this essay I will discuss many pro’s and con’s of cloning. Cloning can help the human race in many ways, but is it necessary? One way it can help us is by the cloning of plants and animals. In doing this, we could create more food and genetically engineer the food to maximize its health. "Commercial livestock cloning could inundate the food supply with novel products that have not been safety tested."(Mendelson). Most scientists who oppose the idea claim that cloned animals usually have birth defects, and have not been properly tested for safe consumption. Although this could be true, with the rapidly advancing technology in today’s world it probably will not be long until cloning is perfected, and the animals pass all tests. However, is the cloning of animals really necessary for us to survive? Those who are on the more ethical side of the matter believe that God has and will continue to provide us with plenty of plants and animals to survive on. Thus, the argument can go back and forth depending on your beliefs and personal ethics. Ultimately the answer to the question is what you make it. Another way cloning can benefit us is by the cloning of......

...Cloning Should cloning be funded by the government? I for one believe the U.S. Government should fund cloning because cloning can cure disease, endangered species could be saved and we’re taking steps towards immortality. The U.S. Government should fund cloning because cloning can cure disease. Cloning has been proven to recreate cells that may not function correctly. ACT’s Dr. Robert Lanza predicted that work like his will revolutionize the field of medicine, providing novel treatments for Alzheimer’s, diabetes, heart disease and Parkinson’s. A tiny cluster of cells, smaller than the head of a pin, holds the key to curing fatal diseases, even to growing spare body parts, says Lanza, director of medical research at the labs. (Cloning) The U.S. Government should fund cloning because cloning can save endangered species. Organisms can reproduce with a “clone” to make offspring. When an endangered species can’t reproduce fast enough to stop extinction scientist believe cloning can save species. Imagine it is the year 2050, and only 30 cheetahs are left in the world. Tireless efforts to help the animals reproduce in the wild have failed and the species could soon die out. But there is a lifeline, and it's in the freezer. Scientists turn to thousands of cell samples collected from cheetahs over the years since 2002, and one by one each of these animals is reincarnated with the help of cloning. This vision is anything but fantastical. If all else fails, such as habitat......

...Cloning DNA cloning has given major insights into understanding the genetic makeup of an organism. The cloning process will allow the alteration of DNA to better the organism in ways like nutritional value or resistance to diseases. DNA cloning has opened new doors to the studies of genetics. In order to clone DNA, there is a specific method in which selective amplifying is required of DNA sequences, which would in turn generate homogenous DNA populations (Strachan & Read, Chapter Chapter 4, 1999). Cell-based DNA cloning was the first type of DNA cloning to be developed. Foreign DNA fragments in vitro are attached to DNA sequences (Strachan & Read, Chapter Chapter 4, 1999). The new product of DNA is referred too as being recombinant, which just means that the DNA is linked sequences that originate from different sources. Those recombinant DNA fragments are transferred to host cells, which is where they are cloned. These host cells in which recombinant DNA fragments are transferred to must be able to replicate (Strachan & Read, Chapter Chapter 4, 1999). However, in order for DNA to be able to replicate, it must be able to have an origin of replication. In DNA cloning, most is done using modified bacterial or fungal host cells. They are primarily used because they have a higher capacity for rapid cell division (Strachan & Read, Chapter Chapter 4, 1999). The replicons have to go through many cycles of replication even though bacterial cell hosts only have one......

Human Cloning

...Cloning is paradigmatic because it signifies both a specific medical technique and the mode of operation of modern technique. As a specific technique it allows the reproduction of biological organisms, including humans. As a mode of operation it signifies the turning of given phenomena into human-induced processes, and in doing so seeks to control, if not outright eliminate, otherwise given differences. In the latter sense, cloning is equally applicable to biological organisms and cultural artifacts, including law. Seen from this perspective the homogenization of international law in the field of biotechnology is a telling case of the cloning of international law. The essay will begin with a science fiction account of cloning through a brief discussion of Aldous Huxley’s novel Brave New World.17 I will then move to discuss two case studies of genetic regulation, which simultaneously address the problem of cloning and reproduce the problem on a different level. The first concerns human cloning and the 2005 United Nation Declaration on the Human Cloning.18 The second concerns stem-cell research and a more recent decision of the Court of Justice of the European Union (CJEU) in the case of Brüstle v. Greenpeace (2011), to impose a blanket prohibition on patenting the outcome of stem-cell research. The two cases represent the growing international governance of biotechnologies. Both regulations set limits on the use of specific biotechnologies either by an outright prohibition of...

...The first thing that usually pops into someone’s mind when they hear the word cloning is a human replication such as the army of clones in the movie Star Wars. What most people don't know is that there is so much more to cloning than creating a living being identical to the original. There are multiple ways to utilize the technology of cloning whether they be beneficial or not. Cloning is a good idea as long as it upholds life and is not allowed to limit the diversity of genetic traits. Cloning is “the asexual production of an exact copy of an original” (“What is cloning”). It is from one parent and results in identical cells. Scientifically speaking, one cell could be cloned, as well as organs, plants, even animals and perhaps humans. Just as varied, are the reasons to clone in the first place. The possibilities of cloning range from medical uses, personal uses, agricultural and livestock improvement to saving endangered species and more. The medical advantages cloning provides extend life, treat illnesses, and produce medications. Research into cell growth and genetics adds understanding into diseases such as cancer and how to avoid hereditary defects. In addition, cloning can improve food sources whether crops or livestock. Cloning also takes part in choosing desirable traits for people, animals, and plant, crops. Once they genetically engineer the plants, they can clone those seeds so that they have multiple identical copies of that same plant. Same with animals or......

...o Almost everyone has wished that he could have a clone of himself to do homework while he goes out with his friends. Now we have the technology to make this wish come true. Cloning is the creation of an organism that is an exact genetic copy of another. A) Some of the reasons people give to justify cloning are medical purposes, reviving endangered or extinct species, reproducing deceased pet and finally cloning humans. B) Whatever the benefits of human cloning are, I believe that there are serious risks which could even endanger the life of human kind. Therefore human cloning should not be allowed. o There are several arguments against cloning A) One is “the health risks from mutation of genes” 1) An abnormal baby would be a nightmare come true. A particular worry is that the genes used from an adult to create a baby would continue to grow, so that on the day of birth, the genes would be as old as the adult. But many attempts at animal cloning produced disfigured monsters. For example this is a cloned calf which was born in this way and died after a while. This is a mouse with an ear on its back, created by scientists. 2) However, some abnormalities may appear long after the birth. Even if a few cloned babies are born apparently normal we will have to wait up to twenty years to be sure they are not going to have problems later – for example growing old too fast. B) There are also emotional and ethical risks 1) What......

...Cloning 1. What should Dr. Smith do? I think that with such minimal overall research done in the entire cloning industry and no research done with a human being the variable, it is not a wise decision for Dr. Smith to proceed with cloning the body cell of Lucy. Although I don’t think that any further damage (besides death) could happen to Lucy, if something terrible happens or if the procedure does go well and then Lucy becomes ill or something else goes wrong with the cloning in the long run, Mr. Luning could come back after the doctor for damages or just create a bad reputation for Dr. Smith and she could lose and donation or funds that she currently has while cloning animals. 2. Give three reasons she should not do this. 1. Risk – Something could go wrong with the cloning and cause a hardship on future funding and views on Dr. Smith 2. Emotion damage – No longer working on an animal, a procedure that goes wrong could cause the doctor to no longer work towards more research in cloning. 3. Ethics – Many people and maybe even the doctor towards human cloning, could have feelings against a human cloning. 3. Give three reasons she should 4. Success – If everything goes right with the cloning she could be forever known as the pioneer in human cloning. 5. Financial – With Mr. Luning willing to pay everything he has for the procedure, with it being successful many other possible client would present themselves for the......

...The Cloning Debate The first attempt in cloning was conducted in 1952 on a group of frogs. The experiment was a partial success. The frog cells were cloned into other living frogs however, only one in every thousand developed normally , all of which were sterile. The rest of the frogs that survived grew to abnormally large sizes. In 1993, scientist and director of the in vitro lab at George Washington University, Jerry Hall and associate Robert Stillman, reported the first ever successful cloning of human embryos. It was the discovery of in- vitro fertilization in the 1940’s that began the pursuit to ease the suffering of infertile couples. After years of research, scientists learned that "in a typical in-vitro procedure, doctors will insert three to five embryos in hopes that, at most, one or two will implant" (Elmer-Dewitt 38). And that "a woman with only one embryo has about a 10% to 20% chance of getting pregnant through in-vitro fertilization. If that embryo could be cloned and turned into three or four, thechances of a successful pregnancy would increase significantly"(Elmer- Dewitt 38). The experiment the scientists performed is the equivalent of a mother producing twins. The process has been practiced and almost perfected in livestock for the past ten years, and some scientists believe that it seems only logical that it would be the next step in in-vitro......

...challenging problems of cell biology. Her creation raised a troubling question: Can humans, too, be cloned? And if so, Should humans be able to play God? Cloning has been an idea that the world has awaited and feared for decades. Cloning has been around since the 1950s when 2 scientists made a frog from tadpole cells. In the 60s, scientists cloned frogs again, but this time using cells from older tadpoles. What has just happened recently is the cloning of a mammal. The sheep named Dolly. A MAMMAL born from a single adult cell. The question is: Is cloning good or evil? Some say this is one of the most remarkable breakthroughs of science history. Man Creates Life. Amazing. But, let's rethink this.. Is the ability for man to create life (in a sense play god), is this a good thing or a bad thing? Why would it be a bad thing? This is an incredible breakthrough of scientific history. This area of microbiology needs to be further explored. There are several advantages that cloning may serve. A child needs a bone marrow transplant within the next two years. You could clone a copy and retrieve the bone marrow. Cloning would give lesbians a way to bear a biological descendant without visiting the spermbank. Perhaps the army could breed stronger, braver soldiers to use just for battle. Let's look at the advantages to cloning mammals: A farmer could clone his prize cow over and over making several copies of it, producing better milk with more nutrients. A shepard could......
