Genetic Engineering Of Maize Essay - 2743 Words

Genetic Engineering of Maize: Modern Genetic Engineering is the process of introducing an external gene from another organism, to affect the newly modified organism. This is called transgenesis. New genes are introduced into the organism, which will code to manipulate existing metabolic pathways, or introduce completely new variants. This will finally result in a phenotypical change in the organism. Examples of preferable traits that could be enhanced by genetic modification in Maize are thinner kernels, plant stem architecture, leaf size, and increase in corn yield. For an organism to be able to express a foreign gene, the genome of each organism must be similar so the genes are compatible in both organisms. At this point, through the use of liposomes, plasmids vectors, viral vectors, pronuclear injection, protoplast fusion, and ballistic DNA injection as means of DNA insertion, it is not currently possible to insert a single specific gene, such as a Bt gene into a Maize plant. Other parts of unwanted DNA are also carried into the Genetically Modified Organism (GMO) which means the effect of the inserted gene can be greater than anticipated. These are called pleiotropic effects, which can be detrimental to the survival and performance of the plant. Antagonistic Pleiotropism is where conflicting genes affect the plant negatively, with some positive attributes, so this must be considered when genetically modifying a plant. For example, inserting a new gene which wouldShow MoreRelatedWe Must Ban Genetically Modified Foods Essay731 Words   |  3 Pagesengineered foods into our diet. Genetic manipulations can result in unanticipated harmful effects, and because genetically engineered foods are not tested sufficiently, this experiment not only jeopardizes the health of individuals, but could also lead to global food shortages and extensive ecological hazards.Due to genetically modified foods unique and unknown nature, there is potential for adverse health side effects. It is impossible to predict the impact of genetic food, it is a matter of waitingRead MoreGenetic Engineering : Genetically Modified Organisms1649 Words   |  7 PagesIntroduction Genetic engineering is the science of making changes to the genes of a plant or animal to produce a desired result (Anon., n.d.). Genetic engineering is being used by scientists for various projects. It is being used to explore and alter the human genome as well as the genomes of other animals and organisms. Genetic engineering is used to create GMOs. GMO is the abbreviation for genetically modified organism, this organism’s genome is altered, using genetic engineering, so that its DNARead MoreImpact Of Gmo Production On Engineering1226 Words   |  5 PagesSection 3: Impact of GMO production on Engineering in the Islamic Republic of Iran According to the International Service for the Acquisition of Agribiotech Applications, the world’s major manufacturers of GM crops are the United States, Argentina, Brazil, Canada, India and China. The latest findings show that the production of genetically modified crops has grown rapidly and after 12 years, 25 countries have assigned 125 million acres of their agricultural lands to raising genetically modifiedRead MoreGeolab1360 Words   |  6 Pagesbegin to mature. 38.2 Q: The seedless banana, the world’s most popular fruit, is losing the battle against two fungal epidemics. Why do such epidemics generally pose a greater risk to asexually propagated crops? A: Asexually propgated crops lack genetic diversity. Genetically diverse population are less likely to become extinct in the face of an epidemic because there is a greater likelihood that a few individuals in the population are resistant. Q: Self-fertilization, or selfing, seems to haveRead MoreDoes Technology Affect Our Environment?981 Words   |  4 Pagesby it, we wonder if this specific technology should be available to any and everyone. The plants that are mostly modified are soybeans, maize, rapeseeds, and cotton along with others lesser of an impact. Almost 40 million tons of soy material are shipped here to the United States each year and is mainly used for feeding animals and producing food additives. Maize is grown in Europe and is also used for animal feed and raw material for starch. Rapeseeds are widespread in Canada and are used for renewableRead Moreâ€Å"Challenges And Risks Of Genetically Engineered Organisms†.1655 Words   |  7 PagesEconomic Cooperation and Development, Workshop on Challenges and Risks of - What Risk Analysis is Appropriate?

As a result to the modification, the plant receives characteristics within the genetic code. Most, GM plants become resistant to pesticides, however there are other variables within transgenic crops. Since the genes of humans, plants, and bacteria are all created from the same genetic material; scientist have a variety of genes to choose from, when modifying. 　　Within plants, genetic modification occurs in steps . â€Å" There are five major steps in the development of a geneticallyRead MoreThe Economic Consequences Brought By The Banning Of Gmos1426 Words   |  6 Pagesdevelop technologies and products.† The most common and well-known type of biotechnology in the food system is genetic engineering, which refers to the manipulation of an organism’s genome. Some of the food we consume today are genetically modified. The most well-known genetically modified organisms (GMOs) are corn and soybeans.

The exploitable gap between yields achieved and genetic yield potential is closing due to these advancements, however yield potentials are increasing at a much lower rate than the expected increase in demand. The increase in food demand means that average farm yields have to reach 70 to 80% of the yieldRead MoreBiotechnology : Genetic Optimization Of Plant Genome And Development Of Biofuel1096 Words   |  5 PagesBiotechnology: Genetic Optimization of Plant Genome and Development of Biofuel On the basis of reverse engineering and reconstruction, the application of CRISPR-Cas technology in the realm of biotechnology remains predominantly in following directions: optimizing agricultural crops, researching plant genome, and developing sustainable and accessible biofuel which relies on the exploration of new biological pathways in algae and corn (Hsu, Lander, Zhang, 2014; Jacobs, LaFayette, Schmitz, Parrott,
