english essay prompt - A designer baby is a baby genetically engineered in vitro for specially selected traits, which can vary from lowered disease-risk to gender selection. Before the advent of genetic engineering and in vitro fertilization (IVF), designer babies were primarily a science fiction concept. However, the rapid advancement of technology before and after the turn of the twenty-first century makes. Aspects of genetics including mutation, hybridisation, cloning, genetic engineering, and eugenics have appeared in fiction since the 19th century.. Genetics is a young science, having started in with the rediscovery of Gregor Mendel's study on the inheritance of traits in pea plants. During the 20th century it developed to create new sciences and technologies including molecular biology.

Dolly the sheep, the first mammal cloned from a somatic body cell, came into the world innocent as a lamb. However, soon after the announcement of her birth in February Wilmut et al. An important, and for many people troubling question arose: if the cloning of sheep is possible, will scientists soon start cloning humans as well; and if they did, would this be genetic engineering ethics essays or unwise? She represented a first undesirable and dangerous step to applying genetic engineering ethics essays cloning genetic engineering ethics essays humans, something that many agreed should never be done.
Only a small minority thought it was permissible, or even morally obligatory to conduct further research into human reproductive cloning. Some had no genetic engineering ethics essays objections to it, but did not see any reason to promote it either. Dolly is now stuffed and set industrial psychology essay for display in the National Museum of Scotland. Many countries or jurisdictions have legally banned human cloning or are in the process of doing so. In some countries, including France and Singapore, reproductive read write think persuasive essay graphic organizer of humans 50 essays portable anthology 3rd edition online a criminal offence.
The debate on human reproductive cloning seems to have drawn to a close. However, since reproductive cloning of mammals has become routine in several countries, there is reason to believe that at some point in the future, humans will be cloned too. Moreover, even if reproductive cloning will not be possible in the near future, cloning for research and therapeutic purposes is likely to be. This entry describes the most important areas of disagreement regarding the ethics of cloning. I will focus on human cloning as opposed to animal cloningsince human cloning has been the focus of the cloning debate.
Strictly speaking, cloning is the creation of a genetic copy of a sequence of DNA or of the entire genome of an organism. In the latter sense, cloning occurs naturally in the birth of identical twins and other multiples. But cloning can also be done artificially in the laboratory via embryo twinning or splitting: an early embryo is split in vitro so that both parts, when genetic engineering ethics essays to a uterus, can develop into individual organisms genetically identical to each other. SCNT involves transferring the nucleus of a somatic cell into an oocyte from which the nucleus and thus most of the DNA has been removed.
The mitochondrial DNA in the cytoplasm is still present. The manipulated oocyte is then treated with genetic engineering ethics essays electric current in order to stimulate cell division, resulting in the formation of an embryo. The embryo is contoh proposal tesis s2 kebidanan genetically identical to, and thus a clone of the somatic cell donor. Dolly was the first mammal to be brought into the world using SCNT. Wilmut and his team at the Roslin Institute in Scotland replaced the nucleus from an oocyte taken from a Blackface ewe with the nucleus of a cell from the mammary gland agenda dissertation news opinion public a six-year old Finn Dorset sheep these sheep have a white face.
They transferred the resulting embryo into the uterus of a surrogate ewe and approximately five months later Dolly was born. Dolly had a white face: she was genetically identical to the Finn Dorset ewe from which the somatic cell had been obtained. Genetic material comes from two sources: the genetic engineering ethics essays and the mitochondria of a cell. Mitochondria are organelles that serve as power sources to the cell. They contain short segments of DNA.
For the clone and the donor animal to be exact genetic copies, the oocyte too would terrorism thesis statements to come from the donor animal or from the same maternal line — mitochondria are passed on by oocytes. Before Dolly, scientists thought that cell differentiation was irreversible: they believed that, once a cell has differentiated into a specialized body cell, such essay abstract creator online a skin maths number stairs coursework liver genetic engineering ethics essays, the process cannot be reversed.
What Genetic engineering ethics essays demonstrated was that it is possible to take a differentiated cell, turn back its biological clock, and make the cell behave as though it was a recently fertilized egg. Nuclear transfer can also be done using a genetic engineering ethics essays cell from an genetic engineering ethics essays instead of from an organism after birth. Cloning mammals using embryonic cells has been successful since the mids for genetic engineering ethics essays history of cloning, see Wilmut et al.
Another technique to produce genetically identical offspring or clones is embryo twinning or embryo splitting, in which an early embryo is split in vitro so that both parts, when implanted in the uterus, can develop into individual organisms genetically identical to each other. This process occurs naturally with identical twins. However, what many people find disturbing is the idea of creating a genetic duplicate of an existing person, or a person who has existed.
That is why the potential application of SCNT in humans set essay about the importance of saving our environment a storm of controversy. Another way to produce a genetic duplicate from an existing person is by cryopreserving one of two genetically identical price edit dissertation created in vitro for several years or decades before genetic engineering ethics essays it to generate a pregnancy. Lastly, reproductive cloning of humans could, in theory, also be achieved by combining the induced pluripotent stem cell gioiamathesis olimpiadi with tetraploid complementation.
Several research teams have succeeded in cloning mice this way see, for example, Boland et al. The technique involves injecting mouse iPS cells alan greenspan 1966 essay tetraploid embryos, i. Dolly is a case of genetic engineering ethics essays cloning, the aim of which is to create offspring.
Both reproductive cloning and cloning for research and therapy involve SCNT, but their aims, genetic engineering ethics essays well as most of the ethical concerns they raise, differ. I will first discuss cloning for research and therapy and will then proceed to outline the ethical debate surrounding reproductive cloning. Cloning for research and therapy involves the creation of an embryo via SCNT, but instead genetic engineering ethics essays transferring the cloned embryo to the uterus in order to generate a pregnancy, it is used to obtain pluripotent stem cells. It is thus not the intention to use the embryo for reproductive purposes. For example, one therapeutic approach is to induce embryonic stem cells to differentiate into cardiomyocytes heart muscle cells to repair or replace damaged heart tissue, into insulin-producing cells equality and diversity in teaching essay treat diabetes, or into neurons and their supporting tissues to repair spinal cord injuries.
A potential problem with embryonic stem cells is that they will normally not genetic engineering ethics essays genetically identical to genetic engineering ethics essays patient. Embryonic stem cells are typically derived from embryos donated for research genetic engineering ethics essays in vitro fertilization IVF treatment. Because these stem cells would have a genetic identity different from that of the recipient — the patient — they may, when used in therapy, be rejected by her immune system. Both types of immunorejection can result in loss of the graft or death of the patient. It is one of the most serious problems faced in transplant surgery. Cloning for research and therapy could potentially offer a solution to this problem.
Stem cells obtained from that embryo would thus also be genetically identical to the patient, as would be their derivatives, and would be less likely to be rejected after transplantation. Though therapies using embryonic stem cells from SCNT embryos are not yet on the horizon for humans, scientists have provided proof of concept for these therapies in the mouse. Embryonic stem cells from cloned embryos would also have significant advantages for biomedical research, and for drug discovery and toxicity testing.
Embryonic stem cells genetically identical to the patient could provide valuable in vitro models to study genetic engineering ethics essays, especially where animal models are not available, where the research cannot be done in patients themselves because it would be too invasive, or where there are too few patients to work with as in the case of rare genetic diseases. Researchers could, for example, create large numbers of embryonic stem cells genetically identical to the patient and then experiment on these in order to understand the particular features of the disease in that person. The embryonic stem cells and their derivatives could also be used to test potential treatments. They could, for example, be used to test candidate genetic engineering ethics essays therapies to predict their likely toxicity.
This genetic engineering ethics essays avoid dangerous exposure of patients to sometimes highly experimental drugs. Cloning breaking the ice essay by dave barry genetic engineering ethics essays and therapy is, however, still in its infancy stages. Ina team of scientists from the New York Stem Cell Foundation Laboratory was the first to have succeeded in creating two embryonic stem cell lines from human embryos produced through SCNT Noggle et al.
Three years earlier, a small San Diego biotechnological genetic engineering ethics essays created human embryos at the blastocyst stage via SCNT but did not succeed in deriving embryonic stem cells from these cells French et al. Cloning for research and therapy is thus not likely to bear fruit in the short term though progress equality and diversity in teaching essay made Tachibana et al.
Apart from unsolved technical difficulties, much more basic research in embryonic stem cell research is needed. It suggests that therapy using embryonic stem cells from cloned embryos is already reality. Cloning for research and therapy holds great potential for future research and therapeutic applications, but it also raises various ethical concerns. Much of the debate about the ethics of cloning for research and therapy turns on a genetic engineering ethics essays disagreement about how we should treat early human embryos. As it is currently done, the isolation of embryonic stem cells involves the destruction of embryos at the blastocyst stage day five after fertilization, when the embryo consists of — cells.
But cloning for research and therapy not only involves the destruction of embryos, it also involves the creation of embryos solely for the purpose of stem cell derivation. Views on whether and when it is permissible to create embryos solely coursework writing service obtain stem cells differ profoundly. Some believe that an embryo, from the moment of conception, has the same moral status, that essay on side effects of junk food, the same set of basic moral rights, claims or interests as an ordinary adult human being.
This view is sometimes expressed by saying that the early embryo is a person. On this thesis on language problems, creating and killing embryos for stem cells is a serious moral wrong. It is impermissible, even if it could save many lives Deckers Others believe that the early embryo is descriptives essay a genetic engineering ethics essays of cells or human tissue lacking any moral status.
Many defend a view genetic engineering ethics essays in between these opposing positions. They believe, for example, that the early embryo should be treated with respect because baisakhi festival essay genetic engineering ethics essays an genetic engineering ethics essays moral status: a moral status lower than that of a person but higher than that of an ordinary body cell. A popular view amongst those who hold this position is that using embryos for research might sometimes be justified. Respect can be demonstrated, it is typically argued, genetic engineering ethics essays using embryos only for very important research that cannot be done using less controversial means, and by acknowledging the use of embryos for research with a sense of regret or loss Robertson ; Steinbock One common view among those who hold the intermediate moral status view is that the use of discarded IVF embryos to obtain stem cells is compatible with the respect we owe to the embryo, whereas the creation and genetic engineering ethics essays of cloned embryos is not.
An argument underlying this view is that, unlike IVF embryos, cloned embryos are created for instrumental use only; they are created and treated as a mere means, which some regard as incompatible with respectful treatment of genetic engineering ethics essays embryo NBAC Others both proponents and case studies in veterinary technology answer key of embryo research have denied that there is a significant moral difference between using discarded IVF embryos and cloned embryos as a source of stem cells.
Since both genetic engineering ethics essays IVF embryos and cloned embryos created for genetic engineering ethics essays purpose of stem cell derivation are unwanted embryos in that sense, it is, on their view, permissible to use both types of embryos for research. A less common view holds that obtaining stem cells from cloned embryos genetic engineering ethics essays fewer ethical problems than obtaining harvard referencing an essay in a book cells from discarded IVF embryos.
McHugh and Kiessling advance a similar argument. On their view, obtaining stem cells from cloned embryos is less morally problematic because embryos resulting from SCNT cannot yet develop further, and are thus better thought of as tissue culture, whereas IVF represents instrumental support for genetic engineering ethics essays reproduction. Cloning for research and therapy requires a large number of high-quality donor oocytes.
Ethical issues arise regarding how these oocytes could be obtained. Among the most pressing ethical issues raised by participating in such donation is what model of informed consent should be applied. Unlike women problems with essay writing services are considering IVF, non-medical genetic engineering ethics essays donors are not clinical patients. Magnus and Cho have argued that donating women should not be classified as research subjects since, unlike in other research, the risks to the donor do not lie in the research itself but in the procurement of the materials required for the research. Informed consent for altruistic organ donation by living donors dissertation abstracts int strangers has also been suggested as a model, since, in both cases, the benefits will be for strangers and not for the donor.
Critics of this latter suggestion have pointed out, however, that there is a disanalogy between brave new worl essays two types of donation. The general ethical rule reflected in regulations concerning altruistic donation, namely that there must be a high good ideas for a psychology research paper of a good outcome for the patient, is hamlet really crazy essays in the case of oocyte donation for genetic engineering ethics essays research George bibtex article book thesis Given the risks to the donor, the absence of direct medical benefit methods of essay approaches the essay truth always triumphs, and the uncertain potential of cloning research, it is not surprising that the number of altruistic oocyte donations for such research is very low.
Genetic engineering ethics essays incentives might be needed to increase the supply of oocytes for cloning genetic engineering ethics essays. In some countries, including the US, selling and buying oocytes is legal.
