Recommended: Ethical issues in genetic research

For much of human history, mankind has never been able to shape and alter its genetic information. But with modern day advances in technology and scientific research, the idea is slowly becoming a reality, and a major concern for many, scientifically, practically, and morally. It is only a matter of time before augmenting genetic information begins to modify humans; doing so could bring about positive change, but more likely, terrible consequences for humanity. Although the manipulation of the human genome through introducing foreign DNA has the potential to assist in health and development of organisms, doing so unrestricted ultimately proves to be unethical and problematic once applied to humans. The genetic code of all life is the basis …show more content…

For example, considering the fact that genes control trait expression in the body, stretches of DNA found to code for lower intelligence or physical strength could be augmented using DNA from other organisms known to produce desirable physical traits. The foreign genetic code would be accepted into the genome, and expressed along with other genes - the now recombinant DNA could therefore be used to raise intelligence, strength, speed, or any other physical quality deemed desirable. (Peacock 12) Moreover, modern genetic technologies can alter an individual’s genome via DNA insertion or removal to the point where regions coding for hereditary diseases such as Huntington’s or Cystic Fibrosis can be completely removed or altered, producing a resistance or even immunity to such diseases. (Adams) This has already been accomplished in recent years; in 2008, patients suffering from the neurological condition Batten disease had the progression of the disease in their bodies slowed by inserting a corrective gene into their bodies, where it was incorporated into their DNA. It is hoped that such a technology can be improved upon and used in the future to help cure diseases such as muscular dystrophy, sickle cell anemia, and hemophilia, and beyond, producing humans who are genetically resistant to heritable diseases.

    A person's individuality begins at conception and develops throughout life. These natural developments can now be changed through genetically engineering a human embryo. Through this process, gender, eye and hair color, height, medical disorders, and many more qualities can be changed. I believe genetically engineering a human embryo is corrupt because it is morally unacceptable, violates the child's rights, and creates an even more divided society.

  • Frankenstein Today

    1112 Words  | 3 Pages

    The more we know about genetics and the building blocks of life the closer we get to being capable of cloning a human. The study of chromosomes and DNA strains has been going on for years. In 1990, the Unites States Government founded the Human Genome Project (HGP). This program was to research and study the estimated 80,000 human genes and determine the sequences of 3 billion DNA molecules. Knowing and being able to examine each sequence could change how humans respond to diseases, viruses, and toxins common to everyday life. With the technology of today the HGP expects to have a blueprint of all human DNA sequences by the spring of 2000. This accomplishment, even though not cloning, presents other new issues for individuals and society. For this reason the Ethical, Legal, and Social Implications (ELSI) was brought in to identify and address these issues. They operate to secure the individuals rights to those who contribute DNA samples for studies. The ELSI, being the biggest bioethics program, has to decide on important factors when an individual’s personal DNA is calculated. Such factors would include; who would have access to the information, who controls and protects the information and when to use it? Along with these concerns, the ESLI tries to prepare for the estimated impacts that genetic advances could be responsible for in the near future. The availability of such information is becoming to broad and one needs to be concerned where society is going with it.

  • Evolution of Human Characteristics

    794 Words  | 2 Pages

    Human characteristics have evolved all throughout history and have been manipulated on a global scale through the use of science and technology. Genetic modification is one such process in which contemporary biotechnology techniques are employed to develop specific human characteristics. Despite this, there are a countless number of negative issues related with genetic modification including discrimination, ethical issues and corruption. Hence, genetic modification should not be used to enhance human characteristics.

  • Genetic Enhancement is Unethical

    1603 Words  | 4 Pages

    Picture a young couple in a waiting room looking through a catalogue together. This catalogue is a little different from what you might expect. In this catalogue, specific traits for babies are being sold to couples to help them create the "perfect baby." This may seem like a bizarre scenario, but it may not be too far off in the future. Designing babies using genetic enhancement is an issue that is gaining more and more attention in the news. This controversial issue, once thought to be only possible in the realm of science-fiction, is causing people to discuss the moral issues surrounding genetic enhancement and germ line engineering. Though genetic research can prove beneficial to learning how to prevent hereditary diseases, the genetic enhancement of human embryos is unethical when used to create "designer babies" with enhanced appearance, athletic ability, and intelligence.

  • Genetic Therapy: Moral And Ethical Issues In Gene Therapy

    1087 Words  | 3 Pages

    Over 40 years ago, two men by the names of James Watson and Francis Crick discovered deoxyribonucleic acid, or DNA. DNA is hereditary material in humans and almost all other organisms (What is DNA?). From this finding, gene therapy evolved. Today, researchers are able to isolate certain specific genes, repair them, and use them to help cure diseases such as cystic fibrosis and hemophilia. However, as great as this sounds, there are numerous ethical and scientific issues that will arise because of religion and safety.

  • The Debate Over Gene Therapy

    754 Words  | 2 Pages

    In September 14, 1990, an operation, which is called gene therapy, was performed successfully at the National Institutes of Health in the United States. The operation was only a temporary success because many problems have emerged since then. Gene therapy is a remedy that introduces genes to target cells and replaces defective genes in order to cure the diseases which cannot be cured by traditional medicines. Although gene therapy gives someone who is born with a genetic disease or who suffers cancer a permanent chance of being cured, it is high-risk and sometimes unethical because the failure rate is extremely high and issues like how “good” and “bad” uses of gene therapy can be distinguished still haven’t been answered satisfactorily.

  • The Ethical Issues of Genetic Testing

    1419 Words  | 3 Pages

    The Human Genome Project is the largest scientific endeavor undertaken since the Manhattan Project, and, as with the Manhattan Project, the completion of the Human Genome Project has brought to surface many moral and ethical issues concerning the use of the knowledge gained from the project. Although genetic tests for certain diseases have been available for 15 years (Ridley, 1999), the completion of the Human Genome Project will certainly lead to an exponential increase in the number of genetic tests available. Therefore, before genetic testing becomes a routine part of a visit to a doctor's office, the two main questions at the heart of the controversy surrounding genetic testing must be addressed: When should genetic testing be used? And who should have access to the results of genetic tests? As I intend to show, genetic tests should only be used for treatable diseases, and individuals should have the freedom to decide who has access to their test results.

  • Genetic Modification In Brave New World

    1779 Words  | 4 Pages

    Genetically modifying human beings has the possibility of greatly reducing/completely eradicating disease and could allow for longer lifespans within the near future. However, there are many issues associated with genetic engineering including being misused for ulterior motives and ethical problems. While there is good that can come from genetic engineering, the many detriments associated with it far outweigh the few positive outcomes. In his novel Brave New World, Aldous Huxley’s idea of genetic modification is far more extreme and unethical than any current real world technologies, but if the technology continues to rapidly grow, Huxley’s future may not be that far off from the truth.

  • John Harris: Genetic Editing

    Genome editing is a genetic engineering where some part of DNA are inserted, replaced or edited in a genome of living organisms, and for the focus of this article by John Harris, is about genome editing of human DNA. John Harris’s arguments in this article are genetic editing should be used to protect the embryo from susceptibility to major diseases and prevent other debilitating genetic conditions from being passed on through them to future generations and that there is no need for consent for future generation as long as good decision are made. Furthermore, he argues that not only the assisted reproduction by means of technology affects reproduction, but all kinds of reproduction affects future generations, through passing on genetic material

  • Genetic Interventions and the Ethics of Enhancement of Human Beings by Julian Savulescu

    3287 Words  | 7 Pages

    The evolution of technology has been hand in hand with the human subjugation of earth, but the question persists, when does the use of technology go too far? Advances in medical science have increased the average human lifespan and improved the quality of life for individuals. Medical science and biology are steadily arriving at new ways to alter humans by the use of advanced genetic alteration. This technology gives rise to the question of how this new technology ought to be used, if at all. The idea of human enhancement is a very general topic, since humans are constantly “enhancing” themselves through the use of tools. In referring to human enhancement, I am referring specifically to the use of genetic intervention prior to birth. Julian Savulescu, in his, “Genetic Interventions and the Ethics of Enhancement of Human Beings,” argues that it is not only permissible to intervene genetically, but is a morally obligatory. In this paper, I will argue that it is not morally obligatory to intervene genetically even if such intervention may be permissible under certain criteria. I will show, in contrast to Savulescu’s view, that the moral obligation to intervene is not the same as the moral obligation to prevent and treat disease. In short, I will show that the ability of humans to intervene genetically is not sufficient to establish a moral obligation.

    In many cases, traditional medicine is not a viable option for treatment and or cure, thus the advancement in biotechnology needs to occur. With the help of Gene Editing/CRISPR, many individuals that suffer from genetic disorders have the possibility of acquiring viable cures (Ginn et al, 2013). The benefits of Gene therapy include repairing mutation, silencing genes, cure immune deficiencies, eradicate disease, replace defective cells and many more treatments are possibilities (Ginn et al, 2013). Essentially Gene therapy holds untapped potential that needs to be attained for human longevity and advancement (Campbell et al, 1998). For example, if both parents carry a genetic disorder, their option of having a child is limited, thus having an the ability to edit out the genetic disorder, so the child can live a long and healthy life would be a revolutionary concept (CRISPR, 2016). Gene Editing may be new concept, but a previous generation to gene editing is gene therapy and with advancement in technology biotech reaching new heights. Gene Therapy has allowed the scientific community to cure immune deficiencies such as “Severe Combined Immune Deficiency(SCID)” , “Adenosine deaminase (ADA) Deficiency” , and other illnesses hereditary blindness, hemophilia are just to name a few (Campbell et al,

  • Genetic Engineering is Immoral

    423 Words  | 1 Pages

    Genetic engineering gives the power to change many aspects of nature and could result in a lot of life-saving and preventative treatments. Today, scientists have a greater understanding of genetics and its role in living organisms. However, if this power is misused, the damage could be very great. Therefore, although genetic engineering is a field that should be explored, it needs to be strictly regulated and tested before being put into widespread use. Genetic engineering has also, opened the door way to biological solutions for world problems, as well as aid for body malfunctions. I think that scientists should indeed stop making genetic engineering for humans, because it will soon prove to be devastating to the human race. It would cause rivalries and tension among different kinds of genetically engineered humans for dominance and power.

  • Human Genetic Engineering

    984 Words  | 2 Pages

    Human genetic engineering can provide humanity with the capability to construct “designer babies” as well as cure multiple hereditary diseases. This can be accomplished by changing a human’s genotype to produce a desired phenotype. The outcome could cure both birth defects and hereditary diseases such as cancer and AIDS. Human genetic engineering can also allow mankind to permanently remove a mutated gene through embryo screening, as well as allow parents to choose the desired traits for their children. Negative outcomes of this technology may include the transmission of harmful diseases and the production of genetic mutations.

  • Debate on Gene Therapy

    852 Words  | 2 Pages

    Genes are made of DNA – the code of life (Gene Therapy- The Great Debate!). The changes in genes may cause serious problems, which we called genetic disorder. In theory, the only method to cure genetic disorders is gene therapy, which basically means the replacement of genes in order to correct the loss or change in people’s DNA. Although gene therapy gives patients with genetic disorders a permanent cure, it is controversial because it has safety and efficacy problems, and raises ethical issues.

  • The Pros And Cons Of Genetic Engineering

    925 Words  | 2 Pages

    Scientists and the general population favor genetic engineering because of the effects it has for the future generation; the advanced technology has helped our society to freely perform any improvements. Genetic engineering is currently an effective yet dangerous way to make this statement tangible. Though it may sound easy and harmless to change one’s genetic code, the conflicts do not only involve the scientific possibilities but also the human morals and ethics. When the scientists first used mice to practice this experiment, they “improved learning and memory” but showed an “increased sensitivity to pain.” The experiment has proven that while the result are favorable, there is a low percentage of success rate. Therefore, scientists have concluded that the resources they currently own will not allow an approval from the society to continually code new genes. While coding a new set of genes for people may be a benefitting idea, some people oppose this idea.
