Genetic Modification : Recombinant Dna ( Rdna ) Technology Or Gene Splicing Essay

“Sixty to seventy percent of all processed foods available on store shelves contain genetically modified ingredients”, according to George Erdosh and Marcia Amidon Lusted in “To GMO or not to GMO? Genetically engineered food has strong advocates and harsh critics.” Genetically modified organisms can be found in most conventional foods processed in the United States, and genetic modification of crops is extremely common on classic Minnesota farms. Crops such as corn and soybeans or even papaya and zucchini are viable for genetic modification. In fact, the definition of (GMO) as reported by Alex K. Rich and Tom Warhol, authors of “Genetically Modified Foods: An Overview,” is, “food in which, at some point during the production process molecules and proteins are chemically altered to give the food more nutrients, a better appearance, and a longer shelf life.” As a matter of fact, a majority of all the foods found at the grocery store are genetically altered. However, many people do not know what genetic modification really is, or that the idea has been around for many years. GMOs are used to control pests and weeds. Therefore, through changing the genetic makeup of the plant, modifications allow for advancements of new technologies that account for the applicability of specific chemicals, as opposed to dated Non-GMO farming techniques.

Genetic modified organisms, or GMOs, are living organisms that, through the genetic engineering process, have been altered to withstand certain chemicals and increase the nutritional value of the product. In fact, the majority of the foods found at the grocery store are genetically altered. Genetic modification is becoming increasingly popular on farms throughout the United States and moving into other parts of the world due to their increasing yield capabilities and pest and weed control. However, this has been, and continues to be, an extremely controversial topic of discussion in the world of agriculture and biotechnology, as well as health food critics, because of potential environmental and health risks.

A new kind of foods called the genetically modified foods has been creating a quiet revolution in the American market for the past several years. Scientists are able to produce these new foods by transferring genes from one organism into another across species boundaries. This new technique has been developed to improve the shelf life, nutritional content, flavor, color, and texture of foods. Since 1994, about 45 genetically modified foods such as tomato, corn, soybeans, canola, and potatoes have been marketed in the United States. About two-thirds of foods that are processed in U.S. contain genetically modified ingredients. So, we the people are consuming these foods without realizing the fact that they are not produced naturally.

The concept of intentionally altering an organism’s DNA in order to produce genetically modified organisms (GMOs) has been critically analyzed by both science and the mainstream media in the last decade. However, the genetic modification of organisms is not a recent innovation as humans have been modifying organisms for over 30 000 years (Rangel, 2015). Back then, breeding through artificial selection was the most prominent method of genetic engineering. Organisms with the most desirable traits would be bred together in order to create a new generation of superior organisms. Throughout the centuries, the developments in science and technology have resulted in new methods of genetic engineering. Now, genomes can be spliced in order to insert or remove genes. It has essentially come down to a copy and paste process with genes from animals being inserted into plants as the common practice.

The UDSA is carefully monitoring the development of genetically modified foods by using a similar testing protocol that is used to approve drugs for the human market. As of 2000, there were over 40 plant species that were approved for commercial distribution in the United States (Whitman, 2000). As the population of the world continues to grow, so does the interest in genetically modified foods as a potential solution. However, there are those that do not agree.

This is where the word genetically modified food comes into place. Genetically modified food or more commonly known as GMOs, is where small amounts of hereditary material (DNA) from different organisms have been added to the original crop or plant which is to be modified through the new addition. The overall topic of GMOs is very hot, there are many individuals who believe in them and there are those who do not support the idea and believe that ramifications are a great risk for the future and should be put a stop to immediately. As of now, the GMOs that are available today have been given hereditary qualities to aim to preserve from bugs, resilience to pesticides, or enhance the crops quality. Practically every food item that can be found in our local grocery store, such as apples, corn and tomatoes are all

Genetically modified crops are an incredibly important issue that everyone should be aware of since it is something we are exposed to at a daily basis. Genetically modified crops also known as GM crops or Biotech crops has been one of the most heated debates of issues within our society. The debate about the safety, concerns and disadvantages of GM crops have raged since the mid 1990 's but this is due to the lack of knowledge of the general public. Many people are unaware of what the GM crops actually are and what they offer. Genetically modified crops are plants that are used in the agriculture and have been modified to initiate a new trait to plants that does not happen naturally in the species. These plants are modified using genetic engineering techniques to enhance desired traits. GM crops are made when genes of commercial interest are transferred from one organism to another.() There are many methods used for the production of GM crops but the two primary used for plant insertion are gene guns and agrobacterium tumefaciens. There are also three types of modifications which are transgenic, cisgenic, and subgenic plants. However, there are a number of issues that surround this controversial topic such as environmental, health, and economic concerns. Even though there are some worrying facts about GM crops people don 't realize the advantages or the ways it has helped humans as well as animals. There are many reasons why GM crops are proven

Genetic modified organisms (GMOs) can be defined as the changing of an organism’s genes by introducing, eliminating, or rearranging specific genes using the methods of modern molecular biotechnology, most of the techniques used are referred to as recombinant deoxyribonucleic acid (rDNA) techniques (CAST). Genetically modified organisms and products derived from them have found international use in the pharmaceutical, chemical, and food industries with no documented reports of adverse impacts (CAST).

Genetically modified food have been the subject of much controversy lately. Genetically modified organisms (GMO’s) are a broad group of plants, animals and bacteria that are engineered for a wide for a variety of purposes ranging from agricultural production to scientific research. The types of potential perils posed by GMO vary depending on the type of organism being modified and its intended purpose (EOH, 2003).

In 1996, the first commercial genetically modified seeds were planted in the United States. The first modified seeds were developed with the hopes that they would produce a higher yield of crops. The plants that grew from these seeds were less susceptible to drought, pests and fungi and were engineered to resist the herbicidal or weed-killing chemicals that farmers sprayed on their land. They were touted as a farmer’s dream come true and farmers praised their untested properties. The seeds and plants that were developed to keep pest insects away were either genetically altered so

What are Genetically Modified Organisms or GMOs? “GMOs are living organisms whose genetic material has been artificially manipulated in a laboratory through genetic engineering, or GE” (Clendaniel). The genetic modification of food is defined as essentially, “any change to the heritable traits of an organism achieved by intentional manipulation,” or more specifically, “recombinant DNA technology, which is the process of removing individual genes form one organism and transplanting them into another organism” (MacDonald and Whellams 181; Kirby 352). This genetic modification or gene splicing is the basis for modern bioengineering. With ever-growing populations the need for food, now more than ever, is in great demand; along with environmental issues related to climate change, bioengineering has been the answer to a multitude of global tribulations. Scientist have created “drought resistant corn and soybeans,” rice with increased nutrients, and “pest resistant plants” (Kirsch 21). It is evident that growing food with GMOs can result in increased availability of crops that are naturally resistant to insects. Along with this, “The Food and Agricultural Organization of the United Nations reports that some GMO foods have been engineered to be more nutritious in terms of mineral or vitamin

The risk of genetic engineering to the human health differs greatly from the conventional selective breeding method, because in contrast to humans and animals, the process of genetically engineering foods contains exclusive chemical enzymes and selective genes from a specific organism. According to, Genetically Engineered Food, by Ronnie Cummins, the original cell is cut, molded and given a copy of a resistance gene; then artificially penetrates the plant cell, instantly becoming immune to combating insects and chemical pesticides. The corporations of genetically engineered seed companies “are pushing for herbicide-resistance genetically engineered seeds”(Cummins, 25), which eliminates threats to the plant. The brilliant idea has lead manufactures

The development of genetically engineered foods began in the 1900s, and has been in United State markets since 1995 (Bredahl 18). The most widespread genetically modified foods are oil, maize, cotton, and soybeans (Cunningham 11). Transgenic foods were products created to increase benefit and lower prices (Whitman 2). Genetically modified foods are essential to enrichments of crops (Tan 3). It helps reduce the use of herbicides and pesticides in plants, enhances taste and quality, lower maturation time,

The coding region of the gene is usually fused to a promoter, most commonly used is the 35S promoter from cauliflower mosaic virus (CMV), in order to promote higher expression levels. (Snow et. al, 1997) The popular method for genetic engineering of crop plants is natural gene transfer via an Agrobacterium tumefaciens vector, a bacterium normally found in soils. The transfer-DNA (T-DNA) vector is made by inserting the desired gene fragment in between specific 25bp repeat domains in the bacterium. The vector is then inserted into the Agrobacterium and "the virulence gene products of Agrobacterium actively recognize, excise, transport, and integrate the T-DNA region into the host plant genomes." (Conner et. al, 1999) The amount of DNA transferred is only about 10kb and the nature of the gene is usually well understood. The expression of the gene introduced can also be controlled by adding additional sequences that might allow the gene to be constitutively expressed, expressed only in certain cell types, or expressed as a result of different environmental changes. This method of gene transfer, however, will only work for the natural host range of the bacterium and therefore other methods are used for additional crop plants. Such methods are uptake of naked DNA by electroporation or particle gun bombardment. The use of genetic markers, as mentioned previously, allows for the preferential growth of cultures that contain the new genetic

One industry that plays a vital role in our society is the agricultural industry. The agricultural industry is responsible for the growth of all our valuable crops such as cotton, corn, fruits, other vegetables etc. These crops are planted and then gathered to be sold to consumers. These primary resources are important to our daily lives because they are valuable sources of food and clothing, which are highly needed for our survival in life. Over time, it has been discovered that genetic engineering in plants can be an alternative way to “alter a plant’s genetic makeup” (Nutrition & Weight Control for Longevity, 2005). Why would we want to alter a plant’s genetic makeup? Well, the main reason is to “produce a desired characteristic or weed out an undesirable one” of a plant (Nutrition & Weight Control for Longevity, 2005). Approximately “75% of processed foods contain at least some genetically engineered ingredients” (Nutrition & Weight Control for Longevity, 2005). In the United States, soy beans, cotton and corn are among the many crops that are genetically modified to “resist common herbicides” (Nutrition &
