- Biotechnology has made great improvements within the last few decades. There has been much hoopla recently about one major improvement in particular, gene therapy. Although it has brought us wonderful new practices such as in-vitro fertilization, there still seems to be a great deal of scandal concerning how far scientists with go in their quest to control natural selection.
- ?To Clone, Or Not To Clone?? Did you ever imagine having a child that is the exact replica of you? Did you ever imagine of having the cure for heart disease or cancer? Well, these fantasies are not far from reach. The way we could reach these fantasies is through a process called cloning.
- Last updated: June 30, 1998Should Cloning Be Banned? Since Scottish scientists reported the successful cloning of a sheep named Dolly last year, new research into cloning has grown rapidy — as has the ethical controversy surrounding the procedure. In May 1998, scientists at a Massachusetts cell research firm announced the production of genetically identical calves using a new cloning technology that could make it possible to create “designer” cattle.
- Before we assume that the market for human clones consists mainly of narcissists who think the world deserves more of them or neo-Nazis who dream of cloning Hitler or crackpots and mavericks and mischief makers of all kinds, it is worth taking a tour of the marketplace.
- Cloning, the process of creating a copy of a plant or animal that is genetically identical to the original through asexual means, has sparked some interesting moral and ethical debate. For years, cloning has been used to produce a greater number of a specific type of plant, such as the Macintosh apple trees, which have all been derived from single mutated plant .
- Cloning is the somatic nuclear transfer. It has been used for many years but until now, cloning has not been found to be able to take a full grow adult cow and make it have a calf with the same DNA. This report will inform of the recent studies of cow cloning.
- Until the birth of Dolly the sheep, the first mammal to be successfully cloned, it was thought that the ability to clone an adult human was impossible or would only be possible somewhere in the distant future! But that has all changed with the birth of Dolly and the explosion of advances in the field of Embryology and genetic screening.
- Scientists may now insert a gene into the patients own DNA causing the patient to heal skin, which has been impossible until now, with Genetic-Engineering. I doubt that there have been any real disadvantages with this technology, since it works to heal the patient, but we really can’t predict what kind of medical misfits there will be in the future, using this life-saving technology to their own personal, perhaps evil, advantages.
- Genetic engineering involves the alteration of an organism’s hereditary material in order to eliminate undesirable characteristics or to produce plants with more desirable characteristics. The splicing of genes takes place in order to combine traits that would be unlikely to occur together under ordinary circumstances.
- Cloning humans has recently become a possibility that seems much more feasible in today’s society than it was twenty years ago. It is a method that involves the production of a group of identical cells or organisms that all derive from a single individual (Grolier 220).
- But others argue in favor of continuing human cloning research, of continuing to clone human embryos and perhaps cloning adult humans in the future. Some arguments in favor of human cloning might include the fact that cloned human embryos would make research into genetics and genetically related diseases, and their treatments or preventions, much easier and cheaper.
- Cloning Cloning is the production of a group of genetically identical cells or organisms, all descended from a single individual. The members of a clone have precisely the same characteristics, except where mutation and environmentally caused developmental variation have occurred.
- Anti-technologists and political extremists misinform, and over exaggerate statements that genetic engineering is not part of the natural order of things. The moral question of genetic engineering can be answered by studying human evolution and the idea of survival of the fittest.
- which therefor emade her a “delayed” carbon copy of a parent which had contributed her genetic makeup, with a member of the opposite sex only filling in her genetic makeup wherever it was absolutely necessary in the creation process.
- As a human race, we have pursued constant technological progression and advancement. Indeed, our claim to the title of ?superior race? can be attributed in part to the fervor in which we go about improving our own existence through invention and discovery.
- As our technology continues to advance, new breakthroughs in medicine are discovered. With these new developments serious ethical and moral questions arise. Advancements in genetic engineering, reproductive technologies, cloning, organ transplanting, and human experimentation are all causes of concern.
- In the 1970?s, scientists discovered that strands of DNA could be cut using special enzymes, which could cut out genetic combinations. DNA contains information about genes particular organisms hold. Duplicates of genes are also possible through genetic engineering and are very useful for medical purposes.
- Introduction to Frankenstein? Mary Shelley The ethical debate concerning biotechnological exploration into genetic cloning has created a monster in itself. A multitude of ethical questions arises when considering the effect of creating a genetically engineered human being.
- Among the millions of species that inhabit the planet, only twenty species provide ninety percent of the human food supply (Montgomery 2 ). Since the introduction of genetic engineering, however, livestock and crops have a more productive future. Transfer of engineered genes from organism to organism occurs through hybridization, conjugation, and transformation in microorganisms.
- c) For developing countries “catch 22″ of gene revolution technology is that the Third World countries that most need to develop GM crops can’t afford the technology, and corporations in the industrialized countries that possess the technology can’t hope to recoup their high research-and-development costs and remain commercially viable if they give away their genetic patents.
