Genetically modified material are plants or animals that have been modified in order to achieve some goal, such as maintain a longer shelf life or provide nutrients to humans and animals. According to Doctor Kirpichnikov et al., there are several different ways that scientists modify genes of fruit, vegetables, and animals, such as utilizing the methods of “synthesis of genes, isolation of individual genes or hereditary structures from the cells…, and integration of various genomes within a cell” (1). Genetically modified foods are generally accepted because they have the potential to bring nutritional benefits to consumers and even meet some of the basic food needs of society (Hossain et al. 353).

HISTORY OF GENETICALLY MODIFIED FOODS The genetic engineering of food can be traced back to the mid-1800s. In 1859, The Origin of the Species was published by Charles Darwin and explains information of breeding which became the foundation of genetically modifying fruits and vegetables. Sixteen years later in 1865, Gregor Mendel successfully experimented with the breeding of pees and contributed to Darwin’s knowledge. Approximately fifty years later, scientist H. J. Muller proved that X-rays could generate genetic mutation (“A Brief History…” 1).
Genetic engineering originated in the mid-1800s, but the history of genetically modified food has sped up in more recent years. In 1994, the U.S. FDA, Food and Drug Administration, approved the sale of a genetically modified tomato in grocery stores because natural tomatoes have a shorter shelf life (Woolsey 2). Only two years after that, scientists announced the birth of Dolly the sheep, the first genetically modified animal, and the cloning a Polly, a transgenic lamb. Through the experiments, scientists discovered how to clone animals to create a new protein. Scientists are trying to use the feedback from Dolly and Polly to clone other animals to use as food for humans, but these animals contain toxins that are not safe for human consumption (“A Brief History…” 3). By the end of the
“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.
Genetic engineering is the deliberate modification of the characteristics of an organism by manipulating its genetic material, otherwise known as DNA. Since biochemists Stanley Cohen and Herbert Boyer pioneered genetic engineering in 1973, the process has grown to have numerous applications such as medicine production, for example insulin (Mckinley). However, a main topic of concern is the application of genetic engineering on foods that we eat everyday. By modifying the genetic "blueprint" of crops, it is possible to improve many aspects of agriculture. But with any sort of scientific discovery that allows humans to act as Mother Nature, genetically modifying organisms has been a very controversial topic. Yet our society continues to grow, and the need for the benefits of genetically modified foods continues to grow. Genetically modifying foods should be permitted in our society because it allows larger yields of crops to be produced, produces foods with higher nutritional values, and reduces our global ecological footprint.
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 genetic engineering of foods has, in one sense, been in existence for hundreds of years. The first time Gregor Mendel bred different varieties of pea plants to observe the various traits present in their offspring, the concept was born. Today, genetic engineering has developed into one of the most complex and advanced fields of scientific thinking, all the while provoking many questions and acquiring many opponents along the way. While there are compelling arguments presented for each side of the issue, the simple fact is that genetically modified (GM) foods are a reality, especially in the United States, as they are already present in many products that are consumed on a daily
There have been ongoing debates about the adoption of GMOs over natural food growth. Out of these discussions, there is a rising need to do research on genetically modified food verses naturally grown food. According to (Mary Colson., 2017), Genetically Modified food can be defined as a growing plant or animal that is modified and grows not a normal, natural way. The growth of this plant, animal or microorganism is triggered by altering its genetic material. The genetic material is usually changed in a way that makes the food not to occur naturally through natural recombination or mating in this particular case. Genetic modification of food has its pros and cones. In this discussion, the advantages and the disadvantages are discussed as
From prehistoric times crop plants and animals have been improved by selective breeding, a process by which humans breed other animals and plants for certain traits, but the modern marvels of GMOs and transgenic plants have come to light in just the last few decades. Selection procedures have achieved huge differences in form and genetics of a single species for instance the mule, a cross between a male donkey and a mare has been used in Europe for more than 3,000 years (GM Education). Modern genetic engineering started back in 1973 when Stanley Cohen, Annie Chang and Herbert Boyer created the first genetically modified DNA organism. In terms of food, genetic engineering simply means
Many Americans consume thousands of pounds of genetically modified foods every day. Throughout the 21st century, genetic engineering tremendously impacted new research in pharmaceutical and forensic science. During that time, it also revolutionized the food in America and many other countries around the world. Using Recombinant DNA biotechnology on crops and farm animals helps improve nutrition and quantity of foods. However, crops that are altered with hybrid genes can also contain chemicals harmful to humans. By using developed biotechnology, scientists are able to inject viruses and bacteria into the embryos of plants to produce genetically modified crops (). The same is applied for transgenic farm animals to increase the size of the
“70 percent of our corn farmland and 93 percent of soy farmland are planted with crops genetically engineered to resist pests and herbicides and increase crop yields. 60% of all the processed foods in the United States are genetically modified; a shocking statistic has the concern of many Americans. However, most people are uninformed about the beneficial impact that genetically modified food has on their diet. GM is the use of molecular biology technology to modify the inherited structure of organisms. Genetically engineered crops increase nutrients, drought tolerance, provide more food for growing populations, and resists diseases and pesticides. Genetically engineered foods are crucial to the improvement of economy, agriculture, society, and health choices. The creation of GM foods was one of the most significant breakthroughs in food industry. Genetically modifying foods is a key component that is harmless for the enrichment of our foods.
Many people today are often amazed by the amount of nutrition and health information required for humans. The constant stream of genetic modification of food can be confusing. Genetically modified (GM) foods are plants and animals that have had their genetic makeup artificially altered by scientists to make them grow faster, taste better, last longer and to provide more nutrients. Scientists make these alternations by transferring genes from one organism into another in order to change the condition or character of the receiving organism. This process is known as biotechnology or genetic engineering (GE), and it has revolutionized the way that agriculture is practiced in many parts of the world. Researchers are now able to use GE
With only a 20-year history, genetic engineering is only a young science with much uncertainly relativity compared to other fields. Much of the elements bioengineering studies and experiments, the DNA genome and sequence, are still unknown to the scientific community. Changes in genes greatly transform the condition, structure, and essence of an organism, giving us an entirely different and unnatural creation. Even when the physical effects are barely noticeable or deemed safe and ethical, these modified creations’ effects on the environment are impossible to predict and will only emerge when the damage done becomes evident to the human population. Though a large unknown looms over modifying genes, bioengineering industries insist upon dismissing the scare over genetic foods with the vast potential “miracle” foods can benefit upon human society.
This paper reviews the biotechnology of genetically modified (GM) foods, history, benefits and risks. Beginning with the history of biotechnology, the scientific explanation of genetically modified organisms and the risks and benefits associated with the use of genetically modified plants in agriculture, it provides an overview of GM foods. Plant biotechnology has been in use for the last thirty years in the United States and over 150 million hectares of GM plants are grown in 25 different countries around the world (Bertheau 2012). It is reasonable for consumers to have an understanding of GM foods and what they are eating on a daily basis. There is much controversy surrounding the ethical issues and attitudes regarding the use GM plants in our agriculture, however this paper will only focus specifically on the development of GM foods and the evidence-based risks and benefits.
Have you ever thought about the science perspective in the food you eat ? We know science plays a major role in life. Science has made a big change in life throughout the years. Using biotechnology and food contaminations in our food productions, there have been food genetically altered. We know vegetables and other food we buy are bigger in size than usual.We also know the shapes of these vegetables and fruits also look different. We know food production companies and farms inject chemicals into them but we never go into further details understanding why the food we eat is like that. The food we eat are mostly all genetically modified. Genetically Modified foods are used widespread throughout the world. There have been many changes to the food we eat with the use of technology.There has also been differences in the way food is grown and produced. Many foods people buy at grocery stores are genetically modified and people are unaware of that. They are modified to increased longevity ,for greater resistance to pests and viruses, shortening ripen foods and also to make food taste better with higher nutritional values. There are techniques used when food is being genetically modified. A. genetic material (DNA) is altered by adding specific genes. It is through genetic engineering in which the process of artificially modified genes are cut and spliced DNA. Genetic engineering is done to
The use of genetic modification of organisms is the process of extracting deoxyribonucleic acid from an organism and combing fragments (genes) of it with DNA of a separate organism. Consequently introducing new characteristics into the separate organism which alter its phenotypes and genotypes, furthermore when bred it will provide it’s offspring with different genotypical and phenotypical traits due to its parent/s alteration. The repercussions of genetic engineering with the intentions of increasing food production can vary in numerous ways. Evidentially the altering of organic natural material into something suggestively artificial and synthetic is popularly revealed as hazardous. Considering this, people often demand food in its natural form, despite GMO’s exceptional properties.
Modern genetic engineering (GE) and plant hybridization can trace its roots to a 19th century Austrian monk named Gregor Mendel, whose pioneering studies on garden pea plants revolutionized the comprehension of how heredity and the transmission of genetic traits function (Schwarzbach, Smykal, Dostal, Jarkovska, & Valova, 2014). However, it was not until Watson and Crick (1953) that the double helix structure of DNA and the composition of chromosomes were identified. With this knowledge, scientists then sought novel ways to more efficiently manipulate an organisms’ genetic sequence, eventually leading to a California-based company named Calgene to introduce the first genetically modified (GM) food, the Flavr-Savr tomato, to the consumer market in 1994 (Redenbaugh, Hiatt, Martineau, & Emlay 1994). Genetic engineering is largely carried out by recombinant DNA technology and allows scientists “to add one or a small number of genes from essentially any organism to simple bacterial cells” (Knight, 2015). Once genes are inserted into the bacterial cells, they can then be introduced into another organism. Foods have been genetically modified, since the production of the Flavr-Savr tomato, to serve specific functions. The functions most closely associated with GM foods have been “improved seed yield, shorter stems that better resist wind damage, herbicide resistance, frost resistance, salt tolerance” (Bennett et al., 2004).
