The Pros And Cons Of Genetically Modified Organisms

Improved Essays
A Genetically Modified Organism (GMO) is an organism whose genetic material has been altered using genetic engineering techniques like recombinant DNA technology, microinjection, bio ballistics, and electro and chemical liquidation. Genetically modified organisms have many positives like being pest restraint, herbicide tolerant, disease resistance, cold tolerant, good nutrition, pharmaceuticals and phytoremediation. Although the crops have so many positives there are some negatives like environmental hazards, human health risks, economic concerns. So what implications does this application of science have on our moral, ethnical, social, economic, political, cultural and environmental factors? So should the modification of an organism’s genetic …show more content…
Modern farmers use techniques like Genetic Engineering, plasmids and vectors, plasmid, vectors, Electro and chemical poration, Bio ballistics method and Microinjection. Many crops and organisms are genetically modified like soybeans, Maize, Wheat, canola, sugar beat, potatoes, rice, cotton, meats, milk, tomatoes, squash, rice, oils and salmon. The genetic modification of these crops make them grow faster, change the shape and size, become pesticide resistant, able to grow in different weather conditions, resistant against pests, increase nutritional value, virus intolerant and can change the colour. Tomatoes were the first genetically modified food to reach supermarkets, although since reaching the market they have been altered to make them last longer. Genetically modified tomatoes can last longer amounts of time before going off, which means they can be transported. They can also be left longer before being picked and mature which results in a higher quality taste. The Genetically Modified tomato was developed by a California based company called Calgene. They genetically modified the tomato through the recombinant DNA technique adding an antisense gene. This gene hindered the production of the enzyme polygalacturonase. This stopped the tomato rotting and slowed the ripping

    Genetically modified organisms created by genetic engineering began with Watson and Crick’s model of DNA. “Some benefits of genetic engineering in agriculture are increased crop yields, reduced costs for food or drug production, reduced need for pesticides, enhanced nutrient composition and food quality, resistance to pests and disease, greater food security, and medical benefits to the world’s growing population” (Phillips). All of these advancements have allowed farmers to enjoy a larger and more profitable…

    GMOs themselves also date back much further than the late 20th century, with products like the famed “Winter Wheat” mentioned previously being planted more than half a century earlier. Though not a modification in the modern sense, strains like the weather resistant grain were created through a process with an identical end result known as selective breeding. Selective breeding is the cross pollination of plants with more desirable traits to create improved versions of those plants. It was practiced unintentionally thousands of years ago, due to a lack of understanding of the genome. However, it was soon understood in practice that traits were somehow passed down through generations of crops.…

    Scientist have expanded the shell life of tomatoes by inserting a gene into its DNA. There are also other crops that have been modified to resist pest without the use of harmful pesticides. Pesticides can unintentionally alter the balance of the ecosystem by killing various of species or contaminating clean water. However, there is a growing opposition to genetically modified organisms on the basis of health.…

    Selective breeding has been performed for tens of thousands of years. It is when a farmer takes the best crops from his produce and uses them for his next round of farming. While selective breeding can create better produce, it can be very random and take a long time to create a better produce. Also, it is seen as a more natural and safe way to create a better produce. However, GMO technology is much faster and is much more precise.…

    “Genetically Modified Organism” is an article that defines genetically modified organisms (GMOs), explains genetic engineering and biotechnology, and describes the types of GMOs and the potential advantages and disadvantages of GMOs. According to Paul Phifer (2011), the author of “Genetically Modified Organism”, a GMO is: “an organism whose genetic structure has been altered by incorporating one or more single genes from another” (para. 1). This article further explains that DNA, deoxyribonucleic acid, is the molecule (in most organisms) that contains genetic information (Phifer, 2011). Sections of DNA made up of exons, nucleotides that code for genetic instructions, form genes. These exons can be rearranged, added or removed due to catalysis caused by specific enzymes.…

    (Journal 1) 'It is probable that crop improvement began as soon as farming did' (1) It is thought that improvement to crops and harvesting developed subconsciously with farmers selectively breeding animals and isolating, to then reproduce crops from those with the most desired attributes and from highly variable populations.(1) The first genetically modified crop was the tomato Flavr Savr, produced by a Californian company Calgene, in 1992 whose 'intention was to create a vine-ripened tomato that was both 'long-lasting and tasty'. (6) However the company failed to prevent the skin of the tomato from soften whilst the fruit ripened. It took 10 years for the development of the tomato, (6) but eventually it received FDA approval in 1994…

    Genetically modified foods are those that have been made from organisms whose DNA has been altered through genetic engineering. GMO’s (genetically modified organisms) are becoming commonly used on cash crops that are produced in abundance. For instance, the U.S. uses GMO’s to assist in the production of 90% of it’s corn, cotton, and soybeans. GM foods present several benefits. Their use requires the use of less chemicals agents and pesticides, GM foods have longer shelf sustainability than non GM foods, and the seeds can be modified in numerous ways from insect resistance to mineral…

    Genetically modified crops are plants that have had their DNA altered to institute new traits they usually would not have. Crops are modified to resist diseases, environmental conditions, pest and longer lives. The first plant modified was a tobacco plant in 1982. It was produced to be antibiotic resistant. Most of the genetically modified crops in agriculture consist of manufactured goods crops, like soybean, maize, cotton and rapeseed.…

    Genetically modified organisms, also known as GMOs is a huge controversial topic within the public eye filled with ethical, medical, and multiple more topics surrounding the issue of genetically modified organisms. Genetically modified organisms is a group of organisms whose genome has been altered by the techniques of genetic engineering so that its DNA contains one or more genes not normally found there. GMO testing can be done on both plants and animals, in fact, a high percentage of food crops are genetically modified in modern society, and this is because of the research boost on genetic engineering in 1996. Genetically modified organisms are created by choosing the trait of interest, isolating the trait, placing the trait into the desired…

    For example: insecticidal toxin from the bacterium Bacillus thuringiensis has been transferred into tomatoe plants to be resistant to the tobacco hornworm (a very damaging pest) the tomato fruit worm (also called Heliothis zea), the tomato pinkworm and the tomato fruit borer (Helicoverpa armigera), all of which destroy tomatoe crops by feeding, ovipositing and spreading pathogens. Another gene called cysteine proteinase inhibitor has been transferred into tomatoe plants, making them resistant to another harmful pest called nematode. Another ceropin B gene has been used to make tomatoe plants resistant to bacterial wilt and bacterial spot. Scientists are still working on finding new genes that can be inserted into tomatoe plants to make them resistant to even more pests and diseases. Genetic modification is a very sofisticated process.…
