Introduction
There is no doubt that man’s progression and development have been aided by the use of genetic engineering as well as biotechnology. These processes have allowed humans to increase their productivity, efficiency and understanding of ourselves and our surroundings. One aspect which remains unanswered with regards to these innovations is whether they can be traced back to the indigenous knowledge of our forefathers. Biotechnology has been a part of humanity since the dawn of humankind. According to Peters P. (1993) “Through the use of the resources in their environments our forefathers acted as the first biotechnologists by manipulating these resources to better their own lives”. Indigenous knowledge has played an important role in the continued development of humanity by not only serving as a way for us to be able to survive in our environment but it also enabled us, as technology improved, to discover why certain home remedies work allowing us to use this information to create modern medicines for example. Today we have the ability to make changes or possibly improvements to organisms through the use of genetic engineering. Genetic engineering has been the cause of debate worldwide as we try to understand whether it is beneficial to humanity and what harmful side effects it may have going forward.
The Gene and the Chromosome
The gene is defined as “the basic physical and functional unit of heredity” by the Genetics Home Reference (2014). They are made up of long chains of DNA and are responsible for protein synthesis. The traits are defined as “a distinguishing characteristic or quality” by Dictionary.com (2014) are determined by the interplay between genes and the environment of an organism.

...to tailor treatments for individuals. As a result of the ability to map out the human genome it is possible to determine a person’s susceptibility to certain diseases or to manufacture medicines specifically suited to treat the individual while having little to no side effects on them. Wilson Peacock (2010, p.193 – 194) describes “It is possible to receive highly effective treatment suitable to the individual’s constitution”. It improves our ability to detect diseases by creating more precise tools. Biotechnology has developed our understanding of the nature of diseases by allowing us to manipulate them and examine their effects. According to the Biotechnology Industry Organization (2010) “Biotechnology has provided us with 20% of all medicines currently available in stores and pharmacies and it is predicted that this figure will increase to 50% by the year 2015”.
It helps medics to find a direct genetic cause of the patient’s condition and target it with pharmaceutical or other therapies. The technology is used for the identification of DNA sequences that increase risks of current diseases and disorders; with this information carriers can start to make efforts to prevent them before the development of the problem. The video mentioned 200 actionable genes, structures that have direct links with a specific condition. Knowing about their presence, people have a chance to bring in preventive measures like taking anticoagulants in the case of identification of a thrombogenic gene. The technology led to the significant improvement of diagnostics and personalized treatments. It helped to find a rare, life-threatening mutation in case of Beery twins and assign a drug to a girl (Alexis) that returned her to a normal life. In the case of cancer genome sequencing led to the development of genetic drags, which target essential tumor genes and make malign structures to shrink. The video mentioned a product that works with the BRАF protein that induces cells to uncontrolled division; the drug led to the remission in the patient with metastasizing melanoma. Such treatment was effective in the case of cystic fibrosis. In the case of the breast cancer the technology helps to evaluate the aggressiveness of the condition and make a personalized decision about chemotherapy. The video also mentioned the pre-implantation genetic diagnosis – an early-staged technology that prevents the development of inherited disorders in
Manipulating the genes of plants and animals is a feat we have mastered already. We are very close to doing the same thing with humans in an attempt to make them smarter, bigger and leaner (McKibben 22). Gregory Stock, an apostle of human engineering,' said of human germ line engineering, "It touches at the very core of what it means to be human. We are seizing control of our own evolution" (Gianelli 25). Mr. Stock summarized the very basis of genetic enhancement in this quote.
One of the most controversial topics discussed in the world of medicine pertained to the topic of genetic engineering. Some doctors saw it as tool of world destruction, however many of them seeing it as a chance of potential cures and treatments. Charles Darwin first introduced this idea. In his first publication, The Origin of Species, he introduced the idea of survival of the fittest. He stated that evolutionary change was only possible due to the genetic variation between each generation, including the combination of different characteristics. In other words, he wrote that only those who had desirable characteristics, in terms of survival, would be able to pass down their genes. If two bred and possessed desirable characteristics, then the desirable characteristic would strengthen, modifying the genes. Darwin’s theories have been the base of many medical breakthroughs that contributed to genetic engineering. The idea soon influenced medicine, the idea of strengthening the healthy cells and isolating them from the unhealthy ones. The simple idea Darwin discovered had changed medicine as a whole. Today, doctors and scientists are able to manipulate genes in order to create new treatments and cures. Today, Darwin’s discovery changed and saved millions of lives around the world. Despite the fact that genetic engineering can have a negative impact on society, it was an important discovery due to the advancement in conventional medicine.
Genetic engineering has been around for many years and is widely used all over the planet. Many people don’t realize that genetic engineering is part of their daily lives and diet. Today, almost 70 percent of processed foods from a grocery store were genetically engineered. Genetic engineering can be in plants, foods, animals, and even humans. Although debates about genetic engineering still exist, many people have accepted due to the health benefits of gene therapy. The lack of knowledge has always tricked people because they only focused on the negative perspective of genetic engineering and not the positive perspective. In this paper, I will be talking about how Genetic engineering is connected to Brave New World, how the history of genetic engineering impacts the world, how genetic engineering works, how people opinions are influenced, how the side effects can be devastating, how the genetic engineering can be beneficial for the society and also how the ethical issues affect people’s perspective.
The age of genetic technology has arrived. Thanks to genetic technological advancements, medical practitioners, with the help of genetic profiling, will be able to better diagnose patients and design individual tailored treatments; doctors will be able to discern which medications and treatments will be most beneficial and produce the fewest adverse side effects. Rationally designed vaccines have been created to provide optimal protection against infections. Food scientists have hopes of genetically altering crops to increase food production, and therefore mitigate global hunger. Law enforcement officers find that their job is made easier through the advancement of forensics; forensics is yet another contribution of genetic technology. Doctors have the ability to identify “high-risk” babies before they are born, which enables them to be better prepared in the delivery room. Additionally, oncologists are able to improve survival rates of cancer patients by administering genetically engineered changes in malignant tumors; these changes result in an increased immune response by the individual. With more than fifty years of research, and billions of dollars, scientists have uncovered methods to improve and prolong human life and the possibilities offered by gene therapy and genetic technology are increasing daily.
Science and technology are rapidly advancing everyday; in some ways for the better, and in some, for worse. One extremely controversial advance is genetic engineering. As this technology has high potential to do great things, I believe the power genetic engineering is growing out of control. Although society wants to see this concept used to fight disease and illness, enhance people 's lives, and make agriculture more sustainable, there needs to be a point where a line is drawn.
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.
“A gene is a segment of DNA or a sequence of nucleotides in DNA that code for a functional product,” Tortora. Microbiology. p. 575. The syllable of the syllable. These genes not only affect our outlook, but also play a role.
Technology has a significant influence across the world, as it has become a fast growing field. Modern biotechnology has been in the major forefront of this influence. From the discovery of DNA to the cloning of various animals, the study of genetic engineering has changed the way society views life. However, does genetic engineering have the capacity to influence the world to its best abilities? Products, which are genetically engineered, may cause severe negative effects on our society. This industry, carrying the potential of leading us toward the unnatural selection of humans to possibly environmental disasters will put humankind in peril. Society, along with humankind, will be in jeopardy since to genetic engineering has the potential of being disastrous.
It is incredible to see how far genetic engineering has come. Humans, plants, and any living organism can now be manipulated. Scientists have found ways to change humans before they are even born. They can remove, add, or alter genes in the human genome. Making things possible that humans (even thirty years ago) would have never imagined. Richard Hayes claims in SuperSize Your Child? that genetic engineering needs to have limitations. That genetic engineering should be used for medical purposes, but not for “genetic modification that could open the door to high-tech eugenic engineering” (188). There is no doubt that genetic engineering can amount to great things, but without limits it could lead the human race into a future that no one today could even imagine.
It address the questions that are at the center of the medical field, such as what it means to be human, the role of technology in health care, and the boundaries of treatments involving advances in technology. Although human enhancement appears to have several positive affects, the negative affects are also great in number. Neither can be overlooked since this technology has the power to not only improve humanity, but also bring it to an all time low. By considering the factors that play into the outcomes of biotechnology, it is possible to answer the pressing questions at hand and to determine the circumstances in which biotechnology could result in beneficial
The controversy of these issues stems from the immense potential in genetic sciences for both positive use and harmful misuse. Though the questions and fears of critics reflect the wisdom of caution, the potentially unlimited benefits mandate that we pursue these technologies.
Any technological application that uses biological systems, living organisms, or derivatives thereof, to make or modify products or processes for specific use to benefit the lives of humans or other organisms, in bettering their lives.
