Recommended: Benefits of genetically modified crops
The founding of genetically modified organisms was extended through the course of many years. It began in 1865 when Gregor Mendel observed hereditary characteristics in pea plants. Nearly forty years later, Andrei Nikolaevitch Belozersky was the first person to isolate DNA, or “factors”, as Mendel defined it, in its pure state (Life Sciences Foundation, Purification of DNA). This revelation sparked the start to DNA innovations. After the discovery of DNA’s structure by Watson and Crick, scientists continued to crack the code, and DNA modification became possible when Professor Herbert Boyer created recombinant DNA (Chemical Heritage Foundation, Paul Berg, Herbert W. Boyer, and Stanley N. Cohen). He was able to create recombinant DNA by splicing the desired trait and inserting it into a cloning vector which would allow the gene to be transferred and expressed in organisms (HudsonAlpha Institute of Biotechnology, How are GMOs Made?). He continued this work with Keiichi Itakura, a scientist at City of Hope Medical Center, to create the first genetically modified organism. Their creation of “a plasmid that coded for human insulin” called Humulin would soon be sweeping the world with many concerns (Chemical Heritage Foundation, Paul Berg, Herbert W. Boyer, and Stanley N. Cohen). Although it has been debated about widespread health concerns, the production of genetically modified organisms does not impose health risks, but it increases benefits for the agricultural industry, medical field, and economy.
The agricultural industry faces the greatest amount of benefits. Genetically modified organisms enable farmers to produce crops that are resistant to weather conditions. Specifically, genes from the Arabidopsis, a flowering plant related...

Modern biotechnology was born at the hands of American scientists Herb Boyer and Stain Cohen, when they developed “recombinant deoxyribonucleotide, (rDNA), [1] for medicinal purposes. Subsequently, biotechnologists started genetically engineering agricultural plants using this technology. A single gene responsible for a certain trait, from one organism (usually a bacterium) is selected altered and then ‘spliced” into the DNA of a plant to create an agricultural crop consisting of that...
Genetically engineered (GE) food crops have caused heated debate in the food industry for many decades and have caused many consumers major concern. According to Dr. Carroll Rawn, a biology professor at Seton Hall University, genetically engineering food entails taking genes from a certain crop and inserting those genes in the DNA of another. This process changes the nucleotide sequence of the crop and, therefore, its characteristics. The debate lies in the question of whether these changes are beneficial for the productivity and quality of the harvest. Jeremy Rifkin argues in his article, “Science and Technology: O Brave New World,” that GE foods are not beneficial for the environment by stating, “Virtually every genetically engineered organism released into the environment poses a potential threat to the ecosystem” (247). On the other hand, the internet article, “New Research Confirms Environmental Safety of GE Crops,” argues, “A comprehensive review of international research conducted on areas of potential concerns related to genetically engineered (GE) crops concludes that such crops do not provide unique ecological risks and may contribute to ecological benefits such as increased biodiversity.” Increased biodiversity means an increased number and variety of crops farmers are able to produce, which has many benefits, specifically feeding starving people around the world. Thus, it is clear that, while genetically engineered food crops do introduce some dangers to consumers and the environment, their benefits, specifically pest, herbicide, and disease resistant capabilities and the new opportunities they provide through biodiversity, clearly outweigh the...
Genetic engineering has been around for many years and is widely used all over the planet. Many people don’t realize that genetic engineering is part of their daily lives and diet. Today, almost 70 percent of processed foods from a grocery store were genetically engineered. Genetic engineering can be in plants, foods, animals, and even humans. Although debates about genetic engineering still exist, many people have accepted due to the health benefits of gene therapy. The lack of knowledge has always tricked people because they only focused on the negative perspective of genetic engineering and not the positive perspective. In this paper, I will be talking about how Genetic engineering is connected to Brave New World, how the history of genetic engineering impacts the world, how genetic engineering works, how people opinions are influenced, how the side effects can be devastating, how the genetic engineering can be beneficial for the society and also how the ethical issues affect people’s perspective.
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...
Shortly after the groundbreaking discovery of the structure of DNA in 1953, the scientific world was essentially given the ability to alter the genetic sequence of any living organism using a process known as 'genetic engineering'. By definition, genetic engineering is 'the deliberate modification of the characteristics of an organism by manipulating its genetic material', it is quite simply an unnatural process which defies the ordinary course of nature. As of yet, no devastating or permanent damage has been done. However, the unpredictable nature and unknown consequences genetic engineering holds is more than enough reason to be cautious, as one mistake could have irreversible and catastrophic effects.
What many people do not know is that genetic modification has been going on since the founder of Genetics, Gregor Mendel, cross- bred his pea plants for different affects. Many of the flowers sold and bought in our society are mutations and mixing of genes. "The corn we eat today is the result of decades of· self-pollination followed by cross-pollination to produce vigorous hybrid plants" ("History" 3). For well over a century, playing with genes has given humans a more cost and space efficient means of mass-producing plants, whether that is corn, potatoes, strawberries or flowers. The National Research Council met in 1989 to discuss some concerns over field testing of GM organisms (GMOs). A report from the National Academy of Science said, "Crops modified by genetic engineering should pose risks that are no different from those of cops modified by classical genetic methods" (Hokanson 1). These classical methods range from Mendel's cross-breeding to wi...
Genetic engineering has revolutionized over the years and it is being used to improve food, to discover new medicines, to remove environmental contaminants, to recycle waste, and to provide permanent cures for inherited diseases (Le Vine, 1999). The purpose of genetic engineering in the medical field has been to produce mass-produce insulin, human growth hormones, human albumin, monoclonal antibodies, vaccines, and many other drugs (Applications of Genetic Engineering,
The term GM foods or GMO (genetically-modified organisms) is most commonly used to refer to crop plants created for human or animal consumption using the latest molecular biology techniques (Whitman, 2000). These plants have been modified in the laboratory to offer desired traits such as increased resistance to herbicides or improved nutritional content. Also, genetic engineering techniques have been applied to create plants with the exact desired trait very rapidly and accurately. For example, this is done by the geneticist isolating the gene responsible for drought tolerance and inserts it into another plant. The new genetically-modified plant will now have gained drought tolerance as well.
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.
How many of you hear the words “genetically modified food” and immediately think “BAD”? How many of you scorn the idea that genetically modified foods are useful? How many of you have been manipulated by the media to think that all biotechnology is evil? Genetically modified organisms (GMOs) are organisms that have been genetically spliced to achieve a certain trait. As the demand for a larger food supply is increasing due to population growth, the benefits that GMO foods provide are being hailed as the only solution to the food crisis. However, many people are making inadequately informed decisions, and are pushing them to the back shelf. I will inform you on why genetically modified organisms may be the only way to a stable, safe future for the less fortunate.
“Genetically modified foods are a "Pandora's box" of known and unknown risks to humans and the environment. They have been forced onto the American public by multinational biotech and agribusiness corporations without adequate oversight and regulation by the United States government (Driscoll, SallyMorley, David C).”Genetically Modified Food is food which has been chemically altered by scientists during the production process to give the food more nutrients, better appearance, and a longer shelf-life (Rich, Alex K.Warhol, Tom). The importance of this issue is that these GMO’s can actually have a negative effect in our society in general. It could mutate in a negative way and cause cancer or other diseases. Genetically modified food should be strictly controlled due to its various detrimental effects on the environment, human health, and potentially insect/animal effects.

GM crops also benefit the economy and assist in feeding more people. While we struggle with feeding our population, “The population will continue to grow” (Calandrelli 1) For instance, genetic engineering in agriculture can minimize the cost of producing food. Thus, GMO’s in crops can result ...
Genetic engineering enhances plant resistance to drought, salinity, disease, pests and herbicides. The aim is to try and enhance the growth, productivity, nutrient value, and chemical composition of the plants. Chemicals are constantly being developed or improved to enhance the competitiveness and adaptability of crops, and to kill the parasites and weeds which plague the agricultural sector. . This however is not always good as the plant and the pests then become resistant to these new chemicals defeating the purpose of it being used. The new chemicals which are produced to kill these strong pests and weeds may be more harmful to other plants and remove nutrients within the soil in turn reducing the yield of agricultural crops. The benefits of these characteristics are seen in Argentina according to Pelletier (2010) as they use glyphosphate resistant soybean which allowed the comeback of this crop, as the so...
There are 2.5 billion pounds of pesticides being applied to agricultural products each year in the United States. This is ten times more than was applied forty years ago. It is still unknown as to what type of exact effects these chemicals may have on individuals. Some farmers that have been using pesticides in their fields and developed leukemia are finding that the cause of their disease is from inhaling pesticides. These chemicals are still in use today and most of them have never been tested for the short or long-term effects that they may have on humans.
