Pre-implantation genetic diagnosis is a revolutionary procedure that utilizes in vitro fertilization to implant a healthy egg cell into the mother’s uterus after it is screened for mutations or other abnormalities. That way, only healthy eggs can develop to term and become beautiful, bouncing boys or girls. Designer babies have a bright future in the face of science because they are genetically engineered to be: disease free; viable donors for a sibling or parent; and with optional elimination of any severe cosmetic disorders that might develop,—without risk to human diversity in the future.
One of the most well-known, wide-spread, and enigmatic diseases on this Earth is cancer. It sneaks its way into family blood lines and travels down the family tree—unstoppable—incurable—unless someone goes in and takes that malignant gene out of the equation with the help of Assisted Reproductive Technology (ART) such as embryo screening, in vitro fertilization, and pre-implantation genetics. “PGD allows couples at risk of transmitting a genetic disease to ensure their future children are unaffected by the disease without going through the process of prenatal diagnosis…and being forced to make the difficult decision regarding pregnancy termination” (Pray). Doctors can perform a procedure where a single cell out of an embryo is analyzed and screened for diseases and mutations. The cell that is “clean” or has no genetic mutation is then returned to the mother’s uterus and allowed to develop to term—other pregnancy complications permitting—resulting in a healthy newborn child. This baby, at nearly $18,000 a pop, will not develop the colon cancer that runs through his family’s veins because the gene does not occur in his body. It may not ...

Human Genetic Engineering is Morally Justified Essay - ... For example, at the Geron Corporation, a biotech firm in Menlo Park California, scientists have discovered how to make healthy cells will divide indefinitely. They are now working on a project that will result in keeping unhealthy cells from continuing such a division. In simplest terms, at the Geron laboratories, scientists are using genetic engineering to help eventually cure cancer. They are not endangering society, but rather are using genetic engineering for the purposes of good. Any reasonable person would agree that trying to prolong human life by curing deadly conditions such as cancer is a morally justified action; in the same idea, human genetic engineering is currently trying...   [tags: society, benefits, cure, prolong, risks] 810 words

The Benefits of Genetic Engineering Essay - Almost three decades ago, on July 25, 1978, Louise Brown, the first “test tube baby” was born (Baird 1). With this birth another controversy broke out, do humans have the right to make life. Most of the concern comes from the fear of control over the production and development of human beings. But, those who are against cloning would most likely look the other way if they needed gene therapy after receiving a grim diagnosis. There are many aspects of genetic engineering and to thoroughly understand it looking into each is absolutely necessary....   [tags: Genetic Engineering ]

Essay on Genetic Engineering Is Not Ethical - For many years, genetic engineering has been a topic in heated debates. Scientists propose that genetic engineering far outweighs its risks in benefits and should be further studied. Politicians argue that genetic engineering is largely unethical, harmful, and needs to have strong limitations. Although genetic engineering may reap benefits to modern civilization, it raises questions of human ethics, morality, and the limitations we need to set to protect humanity.      Though there is harsh criticism from politicians, scientists continue to press forward saying that genetic engineering is of utmost importance to help and improve society....   [tags: Genetic Engineering is Immoral ]

Genetic Engineering Research Paper - I. Introduction       In the past three decades, scientists have learned how to mix and match characteristics among unrelated creatures by moving genes from one creature to another. This is called “genetic engineering.” Genetic Engineering is prematurely applied to food production. There are estimates that food output must increase by 60 percent over the next 25 years to keep up with demand. Thus, the result of scientist genetically altering plants for more consumption. The two most common methods for gene transfer are biological and electromechanical....   [tags: Science Biology Genetic Engineering Essays]

Genetic Engineering: Our Key to a Better World Essay - What is genetic engineering one might ask and why is there so much moral controversy surrounding the topic. Genetic engineering as defined by Pete Moore, "is the name given to a wide variety of techniques that have one thing in common: they all allow the biologist to take a gene from one cell and insert it into another" (SS1). Such techniques included in genetic engineering (both "good" and "bad") are, genetic screening both during the fetal stage and later in life, gene therapy, sex selection in fetuses, and cloning....   [tags: Genetic Engineering Essays]

Essay on The Benefits of Genetic Engineering - What exactly is genetic engineering. A simple definition of genetic engineering is “the ability to isolate DNA pieces that contain selected genes of other species”(Muench 238). Genetic engineering has been the upcoming field of biology since the early nineteen seventies. The prosperous field has benefits for both the medical and also the agricultural field. The diminishing of diseases, especially congenital disorders, reduction of pollution, eradication of world hunger, and increased longevity are just some of the possibilities which scientists foresee....   [tags: Genetic Engineering Essays] 1146 words
