What can we say about genetic engineering? Most of us fear for the worse and do not know how it works, while others think it will make our future brighter . With the way genetic engineering is changing, people could look out their window in future years and see woolly mammoths roaming freely. Genetic engineering is a process that is performed to add DNA to an animal, human,or plant. The reason being to give an organism attributes and characteristics that it does not already have (Higley). Genetic engineering should only be used for the treatment of serious diseases. It should never be used to alter or improve animals.…
-Genetic engineering is an area in biotechnology that induces cell alterations in any kind of organism. It is based on artificial manipulation and transfer of genetic material from one organism to another. Basically the cells coded in with the new genetic information will pass those selected traits on to their offspring. Genetic combinations might be useful but not often found in nature. Genetic engineering now a days, is used in medicine to produce insulin and growth hormones, for those who lack it. The genes in humans are isolated using enzymes produced by bacteria which cleave DNA at specific base pairs, and then inserted into a a virus. The virus then is inserted into the bacteria DNA, ten the bacteria produces the hormones, which are then collected and given to patients who most need them. The hope for genetic engineering is soon a cure can be found for diseases by either inserting a corrected gene or even performing a genetic surgery. Currently many pregnant women like to have the fetuses screened for genetic defects so it can allow them and there physician to prepare for the arrival of the child who may need to have special needs.…
Genetic engineering often gets a bad rap with changing the natural evolutionary cycle, but it could, with proper guidance, improve almost every aspect of daily life. Advances in the Biotech Revolution have made many things that we had merely considered to be science fiction or a thing of dreams are now possible.The fact of the matter is that genetic engineering is applicable to everyday life while still being ethical and inline with people’s morals.…
Genetic engineering (GE) is also known, as genetic modification is the process of organisms that are genetically modified. In this process the goal is to transfer new DNA to an organism so it can improve its habits and make new cells.…
Genetically modified organisms are made moving the DNA from one species to another. DNA contains genes which code for proteins. For plants and bacteria; restriction enzymes are used to cut a DNA segment from a desired gene source and a bacterium plasmid. They are joined using ligase enzymes and inserted into the plant chromosome or host bacterium. For animals the recombinant DNA is injected into an embryo and transferred to a recipient mother. The organisms will now express a new protein. Proteins determine form and metabolism. Genetic engineering changes the natural DNA of living things, cutting across species boundaries.…
Genetic engineering is the incorporation of a new gene into another organism's genome for a certain benefit which may include treatment of diseases, manufacturing of drugs,hormones etc., and production of foods.It started in early 1900's, but scientists at that time did not practice ethics but as time went by ethical issues were addressed with the evolution of International organizations such as the United Nations. lt has been beneficiary to our society especially in the food production industries in order to feed large numbers of people through Genetically Modified Organisms (GMO),even though there will still be issues of concern on the negative side effects of these products.…

There is debate about whether genetic engineering should be used or not, and to what degree. There are many problems that can occur from the process and many of these cannot be avoided currently. There are known problems and there is also the fact that the whole process is unpredictable and unforeseen problems could crop up. A good example of this was the influence of a genetically engineered organism on a food chain, which sometimes damaged the local ecology. The new organism could now compete successfully against other species, causing unforeseen changes in the environment. This could then have a knock-on effect that could lead to the destruction of whole species.…
Genetic engineering is the modification of an organism’s genome through direct human manipulation of the DNA using modern technology. Although classical genetic methods using selective breeding has been done by humans since thousands of years ago, the manipulation of genome of organism through advance technology has only emerged since 1970s (Wikipedia, 2011). By injecting a foreign gene into an organism, we can alter the properties of the organism to generate higher crop yields, more nutritious food and even production of therapeutic agents such as insulin. However, by date, no technological advancement has been without flaws. Genetic engineering also provides negative impact upon environment and human society. Gene for herbicide resistance may transfer to other plants and causing mutation and the spreading of super weed. Gene therapy, a treatment done to cure genetic diseases by introducing new genes to replace mutated ones, is still under development. The effect of the treatment is short-lived as for now. Moreover, the virus used as a vector the deliver the foreign gene may not be silenced completely, causing to multiply and damage the host. Furthermore, there are still a lot of moral issues under debate regarding genetic engineering being done on human.…
In Brave New World, they used “the liquor in which the detached eggs and ripened eggs were kept” (Huxley 5) . In the real world, genetic engineering would be able to, “work for other genetic disorders caused by a single mutant allele” (New). This could be used to prevent a plethora of diseases, and help countless lives. Science is similar to most things, as it can be used to help or harm. While some do say it can be used for bad, it also can be used to help. How genetic engineering while affect the world is determined by who uses it, and for what ends. If one country bans an idea, it is not banned everywhere, and can never be forced to stop. One can not stop ideas, but ideas can be used at least to learn…
Since the development of genetic engineering in the 1970s, scholars have questioned its ethical justification, claiming that it was playing God’ and was unnatural. Others claimed that humans have always altered their environment to benefit themselves. An example is that of genetically modified crops which some people believe can be justified for a number of reasons. The food has better taste and quality and a greater resistance to pests and diseases; it is environmentally friendly in that it does not require chemical pesticides and will conserve soil, water and energy; and it offers the world’s best chance to end or at least greatly reduce hunger and malnutrition through greater yields and sturdier crops. However, others believe that this kind of genetic engineering cannot be justified because GM crops threaten the environment and may cause havoc through cross-pollination. They could have as yet unknown effects on human health by causing unexpected allergic reactions and transferring antibiotic resistance markers. A potentially more serious criticism is that it leads to the exploitation of developing countries: many farmers are encouraged to grow GM crops and gradually become dependent on the multinational companies supporting them. Also, GM food cannot be seen as the sole solution to world hunger – the problem is far more complex, and questions of injustice in the social situations of today’s world need to be examined. These hugely differing stances on whether genetic engineering is ethically justified are just as evident in human genetic engineering.…
Lets start by looking at the cell and the source of heritable traits. We know that all organisms are made up by cells and that new cells can only spring from existing cells. Cell growth depends upon the production of new cells and within each cell exists DNA. DNA contains the hereditary instructions need for each organism to grow and develop. Every parental organism gives the correct amount of DNA to its offspring. Humans give their children twenty-three chromosomes from each of the parents.…
Genetic engineering has many applications in different fields like medicine, agriculture, pharmacy, etc. Let us have a look at some of the important applications of this technology which carries out the manipulation of genes.…
Genetic engineering is a variety of techniques used to transfer a desirable gene from one organism to another. This means that the required product can be synthesized or synchronized within the new organism. Very often these two organisms are totally unrelated species. The products of genetic engineering are referred to as genetically modified or transgenic organisms.…
According to Kennedy the definition of genetic modification is “the alteration of the genome of a human, plant or animal by the addition of new genetic material. Genetic modifications provide a way of expressing desirable characteristics in an organism that otherwise would not display them; it is the insertion of a gene into an organism, altering the genetic makeup” (1). Originally, scientists wanted to use this technology as a…
