Reproductive Cloning Technology Essay - 1795 Words
Reproductive Cloning Cloning has become a major issue in our modern world, from moral, ethical, and religious concerns, to the problem of financial and government support. Human cloning is one of the most controversial topics, and because of this, many of the new important discoveries and beneficial technologies have been overlooked and ignored. Reproductive cloning technology may offer many new possibilities, including hope for endangered species, resources for human organ transplants, and answers to questions concerning cancer, inherited diseases, and aging. The research that led up to the ability to clone mammals started more than a century ago. From frogs to mice to sheep to humans, reproductive cloning promises many possibilities.â⬠¦show more contentâ⬠¦Gene cloning is a unique and complicated technology that holds answers to many questions, and offers numerous possibilities. The process of gene cloning will provide potential answers for questions and puzzles concerning cancer, aging, and in herited diseases, and will help provide a better tool for scientific health research, human and animal alike. But what exactly is gene cloning? It is a process in which a small portion of genetic information (a piece of DNA or gene) is removed from one organism, and introduced into a host cell (Wong, 4-5). In order to accomplish this, the gene is first inserted into a vector, or small piece of DNA. The vector then ââ¬Å"acts as a vehicleâ⬠(Wong, 4-5) and transports the gene into the host cell. The act of this transportation into the host cell is called transformation, and the host cell becomes known as a ââ¬Å"transformedâ⬠cell. This is where the gene-containing vector is replicated or ââ¬Å"clonedâ⬠into identical cells (Wong, 31-34) Important discoveries led to this ability to clone genes. In 1970, scientists Howard Temin and David Baltimore were able to isolate the first restrictive enzymes, named Reverse Transcriptase, which cut DNA in particular locations (History of Cloning). These enzymes, after cutting the DNA, leave what are known as ââ¬Å"sticky ends,â⬠which are then healed by enzymes called ligase (McKinnell, 8-11). Then in 1972, Paul Berg from Stanford University successfully combined two pieces of DNA to form the firstShow MoreRelatedOverpopulation Is Not Too Late?1729 Words à |à 7 Pagesfound interest in raising consciousness about the issue of overpopulation, but is it too late for the inevitable events that are to come? With the rise of technology that question has become difficult to answer as new advancements continue to do the unexpected and merely the impossible. For instance topics that are now in discussion include cloning of living organisms, colonization in other planets, and cre ation of virtual worlds. Overpopulation as defined by the Merriam-Webster dictionary is ââ¬Å"The conditionRead MoreGenetic Engineering and Infertility1243 Words à |à 5 Pagessperm movement, sperm count. To avoid male infertility you need to live a healthy life style (Mary Land University). There are many ways to cure male infertility. Drug therapy may be used to treat hormonal disorder. Surgery may be used to repair reproductive part. The most recent way to cure male infertility is gene therapy. This technique was first done at mice and it worked. They did it by correcting a defective gene in sertoli cell which help sperm to mature. They nourish the germ cells and produceRead MoreGenetic Engineering Pros And Cons1648 Words à |à 7 Pagesonly in turn make the rich even wealthier and those who are poorâ⬠¦ well it would make them even more poor than they already are. CLONING: PROS: If someone is missing or has a damaged vital organ then you could copy and clone the same organ of another person, then transplant it into the unhealthy bodyâ⬠¦ then that body could be healthy again. Another pro for cloning is the fact that you could clone a bunch of babies and there wouldn t even be a need to have children and waste all that money onRead More Human Reproductive Cloning Should be Banned Essay1043 Words à |à 5 PagesHuman Reproductive Cloning Should be Banned The issues concerning human reproductive cloning are shrouded in controversy, perhaps overshadowing the true advantages of cloning technology. Therapeutic cloning, which is often misunderstood as reproductive cloning, is less controversial than the latter as it does not involve the creating of an individual being. Instead, vital stem cells are extracted from human embryos, in order to generate tissues and organs for transplant. The goal of thisRead MoreShould Cloning Be Allowed?1440 Words à |à 6 Pageshuman cloning is becoming a feasible practice. Recently there has been a successful cloning of a sheep, so scientists start to speculate the different uses of cloning human embryos. The three forms of cloning that stand out are reproductive cloning, therapeutic cloning, and cloning for scientific research. Cloning should be permitted, but only reproductive cloning should be permitted with a limit on the number of babies a person or family can reproduce. The arguments that support cloning dependRead MoreHuman Cloning- Term Paper1576 Words à |à 7 PagesShould human reproductive cloning be accepted? Based from Human Genome Project Information (n.d.), ââ¬Å"Cloning is a term traditionally used by scientists to describe different processes for duplicating biological material.â⬠It means creating a genetically identical copy of an organism. Scientists attempted to clone animals for many years. In fact, there are hundreds of cloned animals existing today. It started in 1952 when a tadpole was cloned. But worldwide attention and concerns only aroused inRead MoreThe Debate of Human Cloning Essay1690 Words à |à 7 PagesThe journey that human cloning has taken has been one of dramatic highs and lows, heated arguments and confusion about the path ahead. When researchers witnessed the birth of the first cloned mammal, they were ecstatic, but this high ended with the tragic early death of this sheep, Dolly, due to abnormalities (Jaenisch 2004: 2787). The initial success and progress in this field fueled scientists to want to do further research into this technology, which would eventually leading to work with humanRead MoreWhat Are the Ethical Issues of Human Cloning1463 Words à |à 6 Pagesregarding the issue of human cloning in countries such as the United States, the United Kingdom and Australia which have made attempts or have done research in reproductive cloning. Countries like Australia have prohibited human cloning in 2006. (NHMRC, 2007) Advocates who involve congress members, editorial writers, fertility specialists...and so on gave benefits of human cloning, yet not enough to justify the moral and ethical issues underlying the controversy.

The copies produced through cloning have identical genetic makeup and are known as clones. Scientists use cloning techniques in the laboratory to create copies of cells or organisms with valuable traits. Cloning is a controversial topic because new areas of science often raise questions about safety. Early experiment
