Do Genetically Modified Crops Have A Place? Society?

Over seventy-five percent of the foods that are buy in grocery stores contain a genetically modified ingredient. Humans have been domesticating plants ever since 11,000 BCE. Scientists have been breeding plants together with traits that are considered beneficial to humans and trying to intensify the traits that help humans survive. By altering the genetic structure directly, scientists can efficiently give it specific traits in a more controlled environment and avoid the hit or miss aspect of naturally breeding the plants. By modifying the crops on a genetic level, scientists can engineer the crops and give it more precise traits. This topic is controversial among the scientific community, like with all the other topics relating to

The goal of most genetic engineering is to increase crop yield and to improve the nutritional content or taste of food. (Powell). Efforts to increase crop yield and nutritional content stem from concerns over feeding an ever-increasing world population (Yang). The first successful GMO was created in 1973, and since then science has developed many techniques which allow for the genetic engineering of a variety of crops ("GMOs: Good or Bad for People and the Environment?"). There are four basic steps to create a GMO: identify a trait of interest to be inserted into the organism, isolate the trait of interesest, insert the desired gene into the organism and finally propagate the newly made GMO (Powell). The process of inserting the genetic trait is of special interest in the context of health risks. The most common method of delivering a new genetic trait to an organisms’ DNA is by way of proteins from various bacteria which “invade the seeds and alter plants by inserting pieces of their own DNA into a plants’ genome.”. Cells are treated with heat or electricity to force them to accept the new genetic material (Powell). Many concerns have been raised over this popular method regarding how this changes the nutritional content of the organism and allergies that may be created as a reaction to the bacterial

Virtually all commercial foods are Genetically modified(GMO) in the United States. GMO’s have been estimated to be in 75% of all processed foods in American supermarkets. These processed foods range from soda to juices, fruits to candy, and even to cereal to condiments. However, with the world population reaching a peaking 71/2 billion, countries all over the world have begun adapting to GMO methods to feed their growing population, but nevertheless there are countries like Japan and Europe who have denounced GMO foods for being unnatural and taboo, and thus giving GMO foods a bad reputation. However, a genetically modified crop starts out as a seed that had its DNA altered in a laboratory to enhance desirable traits such as weather resistance, herbicide resistance, and an increase in nutritional value. Genetic engineering is known for creating plants with the desired trait very quickly and with amazing accuracy. For example, plant geneticists can detach a gene responsible for drought resistance from one plant and put it into another plant. This new genetically modified plant will now gain the trait of drought tolerance. Compared to the traditional breeding methods used by farmers, this is less time consuming and quite accurate. On the contrary to the mainstream idea that GMOs are injected with harmful chemicals, the truth is that no chemicals are sprayed or injected to GMO’s to create genetic modifications. GMO foods have no scientific proof of having any dangerous risks

In a broad sense, genetic modification has been around far as long as agriculture has (about 12,000 years). Throughout history, humans have been crossbreeding similar varieties of plants to create more durable, disease-resistant, and overall satisfactory crops. In more recent history, we have come to understand why crossbreeding was such a successful technique to create a more desirable harvest. From Gregor Mendel discovering heredity in the 1850s, to Watson and Crick unlocking the genetic code in 1954, our scientific understanding of genetics has immensely improved. With modern technology and agricultural practices, GMOs are more prevalent now than ever before. While we do still utilize crossbreeding, today many of our genetically modified organisms are generated and tested for desirable traits in laboratory settings. In these laboratories, scientists are capable of adding or removing individual genes in the DNA to enhance or remove certain traits in the plants. These modification practices have made produce bigger, more durable, more pest resistant, and more nutritious than ever before. However, the increased prevalence of GMOs in our produce has also incited substantial fear from consumers. GMOs are scientifically proven to be safe, yet many consumers still prefer to opt for more expensive organic produce even though it is no more nutritious. On top of that, there is now an increased push to require all produce and food products containing any genetically

From the beginning of agriculture, humans have always been experimenting with new ways to produce healthier, tastier foods that last longer and grow larger. However, scientists in the biotechnology industry have come up with a new way to genetically alter foods and other products, by producing GMOs. An acronym for Genetically Modified Organisms, GMOs are organisms that have been genetically modified to show only the desirable traits when they mature. To produce what they call, “transgenic plants”, scientists use recombinant DNA technology (JRSM). They can do this by isolating a gene that produces a specific trait from one organism and splice it into a chromosome from another organism, giving that organism the trait that the first organism originally possessed (PBS). Scientists at Cornell University discovered a way to splice genes into the chromosomes of plants, and that is by using a “Gene Gun” (PBS). Using compressed gas, the “Gene Gun” expels many of the same genes adhered to microscopic balls at a plant. When the balls pass through the plant, some genes stick to the cells of the plant, producing cells that can be grown in culture to produce a “transgenic plant” (PBS).

Once that part of the procedure is done the scientists then must force the new gene inside the cells of the organism, this part of the procedure can be done in multiple ways. The most common tool used in performing

The ability to transform cell cultures and incorporate foreign DNA into other tissues is a key component to studying gene function which allows research to further in biotechnology (Gao and Nielson, 2013). The most commonly used biotechnology methods for integrating foreign genes into plant cells are Agrobacterium-mediated transformation and Biolistic delivery mediated transformation (Gao and Nielson, 2013). For the purpose of this technical review paper, the focus will be on the biolistic delivery method, and primary scientific literature that incorporates this technique in their studies.

Crops are generally modified for one of three reasons: to improve food quality, to make farming more productive, and to create medicine. In each area, there is enormous potential for benefit, but there is also great risk . The first aim of genetic modification is to improve the quality of crops. By toying with the genetic makeup of a plant, scientists can, among other things, increase the size of its fruit and improve its resilience in difficult conditions. These advances have led to greater food accessibility throughout the world; indeed, genetically-modified crops are a tangible potential solution for world hunger. However, some genetically-modified crops were created with much less noble intention. Some genetically-modified seed is constructed with genetic use restriction technology – abbreviated as “GURT” – which prevents seed from germinating. Ethical justification for genetic modification exists if the main aim of such technology is to construct superior quality crops, but utilizing GURT is socially irresponsible and not conducive to improving food quality.

Bt Crops. The next step in genetically modifying organisms for aliment was to ramp up from bacteria – with thin cell walls – to plants that have thick, tough cell walls. In 1976, agricultural researchers at the University of Washington discovered that a diminutive, circular DNA molecule called a plasmid could insert itself into the nucleus of a plant cell and cause tumors. They had discovered what amounted to a natural form of gene

We live in a world that is constantly evolving and adapting due to technological advancements, more specifically in the field of genetic modification. Genetically modified organisms, also called GMOs, are the result of a “laboratory process where genes from the DNA of one species are extracted and artificially forced into the genes of an unrelated plant or animal” (Advani). Anti-GMO opponents argue that this change is altering nature too much, but GMOs have been on the market for nearly 25 years and have yet to produce the epidemic that they are anticipating. Meanwhile, genetically modified organisms have the potential to benefit the field of agriculture as they are continuing to excel in many areas of research. GMO foods should be

Genetically modified organisms have become a standard rather than an exception in America. Since their introduction in the 1990’s, genetically modified (GM) products have conquered agriculture in the United States and hold a large share of the food on American’s plates. (Dupont) Everyone has been exposed to it whether they know it or not. According to the US Department of agriculture by 2012, 88 percent of corn and 94 percent of soy grown in the United States were genetically modified. The purpose of this essay is to explain what genetically modified crop plants are,

Due to the greater understanding of DNA, the field of Agricultural Biotechnology has developed rapidly over the last 30 years. Agricultural Biotechnology is a set of tools to modify products, improve plants and animals, and make microorganism for agricultural uses. It’s being used to produce products cheaper and easy to maintain. More and more farmers and producers used genetic engineered crops because of the price and resistances to insects and diseases. The main aim is to meet human and environmental needs.

Genetically modified plants, or GM plants, are plants that have had their DNA artificially engineered, generally through the synthesis of the plant’s original DNA with that of another organism’s. To do this, contemporary scientists search for the desired gene in an already established and immense database that contains the full genome of a wide spectrum of the known organisms. Once it is found, the gene is usually replicated at an exponential rate due to the utilization of the PCR (polymerase chain reaction). The process includes heating the DNA, which forces it to split. As it cools, primers bind to the strands, thus allowing DNA polymerase to create two complementary strands for each existing strand, thusly creating two identical

Scientist first discovered in 1946 that DNA can be transferred between organisms. Genetic modification is a gene technology that alters the genetic sequence of a living organism such as plants. [1] The combining of genetic material from two different organisms is called recombinant DNA technology. [1] Thus, the resulting organism is said to be genetically modified GM. All of this is to express a gene that may not be native to the plant or to modify endogenous genes. The protein encoded by the gene will confer a particular trait or characteristic to that plant. This technology can be used in many ways from engineering resistance to insect, pathogen, or extreme temperatures. [1,2,6] Another advantage is the technology could be used to improve the nutritional content. [1,2,6]

　　Within plants, genetic modification occurs in steps . “ There are five major steps in the development of a genetically engineered crop. But for every step, it is very important to know the biochemical and physiological mechanisms of action, regulation of gene expression, and safety of the gene and the gene product to be utilized” 1. The first step is mapping; Mapping is locating and isolating the desired gene before extraction. Once the gene is extracted, it must be cloned. Many copies are made of the isolated Gene; gene cloning isolates the gene from the entire extracted DNA. Once it is cloned, the gene of interest is designed and packaged so that it can be controlled and properly expressed inside the host plant. Polymerase Chain Reaction (PCR) is the cloning process, and it
