Cloning and the ability to manipulate and modify DNA has increased immensely in recent years. The field of genetic reproduction is creating a variety of unknown social and ethical consequences that are particular to our present time. Such consequences, although unknown now, of the manipulation of nature at such a primary biological level will have disastrous effects on the generations of the future. Cloning as a new science, concerns itself with the replication of organisms through asexual scientific method creating exact replications of the parent cell. However, cloning in the 90s has developed to the point where manipulation of human D.N.A is a very real prospect and many issues surrounding it must be addressed. These issues and the positive and negative influences on our society will be discussed herein, concentrating on selective breeding, genetic engineering, the identity of ‘clones’, enhanced cell growth products and production of spare body parts.

Firstly, selective breeding throughout the ages has served humanity in many ways. The origins of cloning lie in the agricultural history of humanity. Therefore the perceived gap between cloning and our nature are not so distant, as cloning has been the means by which humankind has cultivated flora for a millennia. In addition, selective breeding has been the means by which humankind has manipulated fauna for its own ends. In both cases genetic manipulation does serve humanity on many practical levels.

Secondly, humankind has genetically engineered many species through selective breeding. The potential of cloning in food production is, if not unclear, certainly unknown to most people. Selective breeding of flora and fauna has continued for eons. Only breeds of preference have been maintained as useful for humankind. The word ‘clone’ finds its origins in ancient Greek. ‘Klone’ (Kreb, 1985 p.164) defined simply in Greek means ‘twig’, a twig that you could place in the ground and the parent plant would be reproduced, better known now as ‘propagation’. Propagation has long been under the influence of genetic engineering in the form of selective breeding. An example of this is barking dogs, it is well known that wild dogs do not bark as such, they howl and growl, domestic dogs on the other hand have been bred to bark, hence barking dogs have been preferable to humankind as they alert the coming of stranger...

Essay on Pros and Cons of Genetic Cloning - Genetic cloning is a subject that has always been popular among scientists. The earliest breakthroughs in cloning can be dated back to over a century ago when a German biologist named Hans Driesch successfully cloned a sea urchin (Wilmut 1). Back then cloning wasn't yet a mainstream topic among the general public. But with all the technological advancements made over the years more astounding breakthroughs have been made possible. This has now sparked a huge debate, not only among scientists, but among governments and the public as well....   [tags: Genetic Engineering]

Essay about Genetic Engineering and Genetic Cloning - A controversial issue is the possible application of new techniques in genetic engineering to produce human clones. Up until now genetic engineering and cloning has been used to clone plants, unicellular organisms, amphibians and simple mammals. This has led to significant advances in agriculture, industry, and medicine. Newer techniques in genetic engineering have enabled scientists to clone more complex mammals and opened up the possibility of cloning humans. Although there are many potential benefits to this technology, the prospect of cloning humans has raised many practical, ethical and religious dilemmas that are currently being debated by society....   [tags: Cloning Essays] 2185 words

Essay on The Role of DNA in Cloning - Have you ever thought that science can advance rapidly to a great extent. Nowadays scientists are trying to make the same exact copy of your DNA. Can you imagine having a clone of yourself, your parents, or even your siblings. Have you ever wished for someone to take your place for a minute, an hour, or a day. This may come true one day. According to the Online Dictionary; a clone is defined as “a cell, cell product, or organism that is genetically identical to the unit or individual from which it was derived.” I always thought that cloning was impossible, and is just science fiction....   [tags: Genetic Cloning, Genetics, Genes] 812 words

Ethics of Human Cloning and Genetic Engineering Essay - INTRODUCTION When the Roslin Institute's first sheep cloning work was announced in March 1996 the papers were full of speculation about its long-term implications. Because of this discovery, the media’s attention has focused mainly on discussion of the possibility, of cloning humans. In doing so, it has missed the much more immediate impact of this work on how we use animals. It's not certain this would really lead to flocks of cloned lambs in the fields of rural America, or clinically reproducible cuts of meat on the supermarket shelves....   [tags: Genetic Engineering Essays]

Genetic Engineering and Cloning Essay - Genetic Engineering and Cloning On February 24, 1997 news broke globally that Ian Wilmut of the Roslin Institute in Scotland had successfully cloned the genetic material of an adult sheep and had created the infant Dolly. The discovery instantly caught the world's attention because Dolly had only one parent; Dolly had been formed by transferring the genetic material of an adult female into one of its own embryos. This process, known as "somatic cell nuclear transfer", refers to removal of genetic material from an adult cell and then implantation of that material into an embryo that has had it's original genetic material removed....   [tags: Papers] 827 words

Genetic Engineering and Cloning Essay - Genetic Engineering and Cloning What are the principle, ethical issues and experimental procedures used in genetic engineering and cloning. Should Cloning be allowed to continue. 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. Advances in technology have raised issues such as animal and human cloning....   [tags: Argumentative Persuasive Topics] 1368 words

Essay on The Reality of Human Cloning - The Reality of Human Cloning As aptly put by Rosa Beddington, the word “clone” has become one of the most emotive of all the terms coined by scientists which have entered popular vocabulary. I shall add another, and that will be the phrase “Dolly the sheep”. The conception of Dolly, the “baby” of scientist Ian Wilmut and his team has opened the possibility of cloning humans. The mention of Dolly brings to average the person, haunting connotations of “future replicas of living megalomaniacs and the resurrected dead”....   [tags: Genetic Engineering Cloning Essays]

The United States Law Banning Genetic Cloning of Humans Essay example - The United States Law Banning Genetic Cloning of Humans Genetic cloning has become an issue in these past years, and many questions have arisen due to this scientific breakthrough. As with any new technology, ethical and moral ideals have clashed between those who support it and those who favor the opposing side. The dispute involves what to do with our ability to clone and manipulate DNA of human beings, plants, and animals, and whether it is ethical for us to pursue research and experiments with genetics or whether it is people just playing "God"....   [tags: Papers] 988 words

Essay on Cloning Humans - Cloning Humans Ian Wilmut’s foray into cloning Dolly has proved to be an appetizing entrée to mankind, with the next step being the cloning of endangered species, and eventually, humans. Although his team of researchers had qualified to the public that it is unethical to clone humans1, the very prospect of being able to replicate creatures of our own kind is nevertheless enticing. Think of all the possible benefits that make many scientists prepared to cross those ethical boundaries: Firstly, couples who have tried a long time for identical twins, triplets (or even quintuplets!) may now be able to have them by producing clones from a single embryonic cell....   [tags: Genetic Engineering Cloning Essays]
