Recommended: Pros and cons of transgenic technology
1. The transgenic technology can be used in many areas. With an in-depth study of transgenic technology, we can use it in many areas. For example, we can use it to make medicine, develop agriculture and clone. Transgenic technology is one of the important areas of life science. It has changed our life gradually. It let us to develop new varieties of products through the extraction and recombination of genes, some of them can provide us more balanced nutrition. Through the cultivation of genetically modified drugs, it is full of medicinal protein, it benefits the patient’s condition a lot, and improve the efficiency of the medicine on the human body. 2. The economic returns to adopt transgenic crops are positive, but highly variable. …show more content…
These all caused by transgenic technology. In the past, it was difficult for us to get organisms of complex structures, such as proteins. But through transgenic technology, we can achieve this goal.Also with the deeper life science laws being revealed and a better biotechnology is coming out, people will have a whole new era of transgenic medicine. 4. Genetically modified organisms have also been developed for commercial use. And help us to learn more about genes. Genetically modified organisms have also been developed for commercial use. Perhaps the most famous example is the food crops, such as soybeans and corn, genetically modified crops and genetically modified crops. Scientists have studied “knock-out” mice,which are transgenic mice that have a particular gene of interest disabled. By studying the effects of missing genes, scientists can better understand the normal function of the gene and how can we improve the uses of transgenic technology. The more we know about genes, scientists can create more useful things for human beings through transgenic technology. 5. Transgenic technology has a very positive affect on …show more content…
Transgenic technology is majorly used for growing petter plants that can inhabit cruel and unnatural habitats. But the thing is that if there Genes are rewritten, there is a big possibility of genetic mutation and might end up creating plants can carry disease that are incurable for man kind and might end up eliminating a variety of
A GMO is a plant or animal that has been genetically engineered with DNA from bacteria, viruses, or other plants and animals. Most of the combinations which are used could not possibly occur in nature on its own. The intention of the process is to create a new beneficial trait such as creating its own pesticide or make it immune to herbicides. This would allow the crop such as Bt co...
Genetically modified organisms are “an organism whose genome has been altered in order to favour the expression of desired physiological traits or the output of desired biological products.” http://www.merriam-webster.com/concise/genetically%20modified%20organism%20(gmo). The United States were first approved for human consumption of genetically modified foods in 1995. The techniques used for producing the genetically developed organisms include cloning recombinant DNA technology. Primary uses of genetically modified organisms are mostly in areas of agriculture and biomedical research. GMOs compromise numerous aids to society, including enlarged crop yields and the development of fresh therapeutic agents which prevent and treat a wide variety of human diseases . However there are some concerns around the use of genetically modified organisms which include the risks stood to human health and the initiation of insecticide resistant superbugs. This essay will provide evidence to support the evidence that the genetic modifications of crops produces better results than selective breeding or mutation.
Genetically modified organisms are created when genetic material is taken from one organism and transferred into another (Young 1). Such materials may pose health risks not only to animals, but also to the environment and
Genetic engineering is now being used to create new medicines and therapies for many disorders and diseases, and also to improve agricultural plants and animals to produce bigger yields or enhanced nutrient composition and food quality. In Gene therapy, copies of healthy human genes produced in bacteria can be inserted into human cells with defective or missing genes, to fix the problem. Gene therapy is promising because it can use to treat genetic
Every year, the rate of mortality increasing because most diseases may lead to death if not treated early. One of the methods that can be used to cure some diseases is by using the treatment known as gene therapy. Based on Pruitt’s (2008) study, numbers of inherited and acquired diseases were reduced since gene therapy has the ability to provide new treatments to cure them. According to Shi and Zou (2008), gene therapy is defined as expression of protein or interrupts the synthesis of protein in cell by transferring the genetic material into a host in order to treat or prevent a disease. Besides that, Kelly (2007) stated that an “abnormal” hereditary disease-causing gene in an individual’s cells and tissues is treated and used gene therapy by to replace them with a “normal” gene. Around 1970’s, idea to use “genes” as “drugs” for human therapy was originally from United States (Giacca, 2010). Moreover, there are some objectives in using the gene therapy as a treatment. First, gene therapy is used to cure or slow the progression of disease by introducing the genetic material into target cells and next objective is to aim at the direct correction of endogenous genetic defects by delivered some additional copies of a gene (Pruitt, 2008; Giacca, 2010). Furthermore, Yadav and Tyagi (2008) found that there are two types of gene therapy which are germline gene therapy and somatic cell therapy. As stated by Shi and Zou (2008), therapy that involved modification of any cells in a patient’s body is called as somatic cell gene therapy while germ line gene therapy is therapy that involved modifying of human eggs or sperms that pass genes on to future generations. Other than that, animal tissue culture is used to test the effective...
Although humans have altered the genomes of species for thousands of years through artificial selection and other non-scientific means, the field of genetic engineering as we now know it did not begin until 1944 when DNA was first identified as the carrier of genetic information by Oswald Avery Colin McLeod and Maclyn McCarty (Stem Cell Research). In the following decades two more important discoveries occurred, first the 1953 discovery of the structure of DNA, by Watson and Crick, and next the 1973 discovery by Cohen and Boyer of a recombinant DNA technique which allowed the successful transfer of DNA into another organism. A year later Rudolf Jaenisch created the world’s first transgenic animal by introducing foreign DNA into a mouse embryo, an experiment that would set the stage for modern genetic engineering (Stem Cell Research). The commercialization of genetic engineering began largely in 1976 wh...
Today, genetic engineering is a powerful and potentially very dangerous tool if in the wrong hands. It can completely change a product that can be very useful, or on the contrary, it is extremely harmful to the people.
In this day and age, Genetically Modified Organisms (GMOs) have become a topic of large interest in the media. GMOs are defined as an organism whose genetic structure has been altered by incorporating a gene that will express a desirable trait (Dresbach et al. al. 2013). Often times, these traits that are selected are either beneficial to the consumer or producer. Currently, GMOs are being created at a higher rate than ever before and are being used in the foods that we eat.
Genetically Modified Organisms (GMOs) are an organism, such as a plant, animal, or any microorganism, who’s had its DNA changed in different ways through genetic engineering that is not natural. It is an organism like every other organism, which produces thousands of proteins, but one or two of them are proteins that were chosen specifically by humans. It creates unstable combinations of plants, animal, bacterial, and viral genes that do not occur in nature or through traditional crossbreeding methods. The majority of Americans in the US consume nearly 200 pounds of GMOs each year. 90% of US crops are genetically modified.
Genetically modified organisms can be plants or animals that have been genetically altered to produce or express a desired characteristic or trait. By genetically altering organisms such as crops, we can eliminate the use of pesticides by making the crops resistant to insects. We can also produce crops that are resistant to floods and droughts. Furthermore, with the use of molecular genetics, we are able to produce foods that are rich in nutrients and supplements. People in developing countries may not be fortunate enough to have a full course meal that contains nutrients from all four basic food groups. However, GMOs can with a little modification provide all the amino acids, vitamins, and minerals included in a good diet by simply consuming a genetically modified staple crop such as rice. In addition, by producing crops that are resistant to harsh environmental conditions as well as pests, we would see a rapid increase in the production of food thereby reducing and or!
Genetically modified organisms (GMOs) are a cause of continuous debate. What would be the purpose of producing genetically altered food? Many argue that GMOs could prove to be very beneficial, the use of GMOs could lead to advances in medicine, and agriculture, and they could also prevent famine in poor underdeveloped countries. Genetic modification offers many benefits: pest control, disease resistant crops, drought resistant crops, no use of insecticides, nutritional beneficial foods, and less contamination. This is only a short list of the many benefits offered by the used of GMOs. With so many benefits why are we opposed to such a miracle? (NERC 2005)
Human Genetic Engineering: Designing the Future As the rate of advancements in technology and science continue to grow, ideas that were once viewed as science fiction are now becoming reality. As we collectively advance as a society, ethical dilemmas arise pertaining to scientific advancement, specifically concerning the controversial topic of genetic engineering in humans.
GMOs, or Genetically Modified Organisms, are perhaps the most practical and handy achievements genetic engineering techniques have to offer. These modified organisms have provided various benefits to humans all around the globe and the Earth itself: they aid small farmers, using less pesticides and yield more; they fight malnutrition, taste better, reduce poverty, and even reverse climate change. GMOs are taking an astonishing role that is positively affecting the world and the people within it with one benefit after another.
Although genetically modified organisms haven’t been around for long, they have progressed a great deal since they were first introduced. Before altering genes was discovered, farmers in the 1800s would selectively breed their livestock to produce bigger offspring of cows or chickens. Modern genetic engineering is built off of the foundation of Gregor Mendel and his work done to pea plants in the 1800s. Mendel bred the pea plants based on color and favorable traits. The idea of breeding plants was in order to create plants with favorable outcomes, for
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.
