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
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.
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
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
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...
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...
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.
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...
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.
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.
People have been altering the genomes of plants and animals for many years using traditional breeding techniques. In recent decades, however, advances in the field of genetic engineering have allowed for specific control over the genetic changes introduced into an organism. New genes can now be incorporated from one species into a completely unrelated species through genetic engineering. Biotechnology is the application of biological research techniques to create new processes and products while using biological systems, living organisms, and/or derivatives of organisms. Many jobs in the fields of industry farming, medicine, and food are being generated from biotechnology. Life can be improved through biotechnology in the following ways: advanced
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
Genetically Modified Organisms, also known as GMOs, are organisms that have had their genes tampered with to gain desirable traits. Desirable traits can include immunity to diseases, quicker growth, or even fattening an animal. GMOs are mainly used in food sources, such as animals or crops; the produce is engineered in such a way that it provides an advantage for the supplier and consumer.
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 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 are now common place in agriculture and medicine. Genetically modified organisms also known as GMO’s are organisms that have had genes from another organism implanted into them. Genetic modification has been in use in agriculture to make plants and animals better producers. In the last ten or so years GMOs have begun to develop other new and unusual uses outside of traditional agriculture. One useful thing being researched is creating goats engineered to produce spider silk.
