Objective Analysis
Genetic Modification is a process in genetic material is altered with methods that do not occur naturally. This process is now possible on plants using Biotechnology, which are called Genetically Modified Crops also know as GM crops. GM crops have the same results as traditional breeding but that is achieved over a much longer time span. In this process, specific individual genes are transferred from one organism to another. These genes may come from a non-related species, for example, a gene from a fish that lives in the very cold seas being injected into a strawberry so it can survive the frost during winter.
There are many reasons as to why crops are modified; it makes them resistant to insects, more tolerant to herbicides. GM crops are designed in one of two ways: They either produce a pesticide within their tissue, or they are resistant to a pesticide like Roundup (manufactured by Monsanto Corp.).
The most common crops modified include Maize, Soybeans, Oilseed rape (Canola), Chicory, Squash and Potato.
A research study conducted by a group of scientists in America shows that Tobacco and Arabidopsis Thaliana are the most genetically modified plant due to well developed transformation methods, easy propagation and well studied genomes.
GM crops are generated in a laboratory by altering their genetic make. This is usually done by adding one or more genes to a plant’s genome using genetic engineering techniques.
There are various types of Genetic engineering in plants. Transgenic plants have genes inserted into them that are derived from another species. Cacogenic plants are made using genes found within the same species or a closely related one, where easy plant breeding can occur.

GMO stands for a ‘genetically modified organism’. A GMO is artificially developed by scientists to produce specific results such as sustain life through a drought or produce a greater quantity of fruit per plant (Monsanto Corporation:1999). This practice began centuries ago when plants and animals were selectively bred and microorganisms were us...
Lee. These modified crops and plants for humans and animals are created mainly to withstand herbicides or to produce insecticides. “No GMO traits are on the market for higher yields, drought resistance, enhanced nutrition or any other consumer benefit” (Burnham). Overall, GE Foods’ main purpose is to save money for large corporations. One of the most prominent crops in the GMO industry is Bt corn.

Because of the increase in population, products need to be manufactured in a faster and more efficient way, and with genetically modified foods, the food is larger in size and quicker to harvest. Another advantage of GM foods is that it uses less fertilizer and less water and is more resistant to insects, diseases, frost, and drought. Consumers would not want to eat food that has been treated with pesticides because of possible health hazards and growing GM foods can help eliminate the use of chemical pesticides. Plants that are genetically engineered to resist strong herbicide will help prevent environmental damage by reducing the amount of herbicides needed. This will benefit both the companies and the environment because the production cost is reduced and the danger of agricultural waste run-off is limited. As more land is being used for housing instead of food production, crops need to adapt to locations unsuited
“Genetically Modified Organisms”, or in other words GMO, is a method of altering mirco-organisms which include plants, fish, yeast, bacteria and mammals. These organisms have been engineered with increased carbon capacity and a smaller need for nitrogen fertilizers. These organisms are made from the DNA of bacteria and the DNA of other plants and animals. Thus genetically diverse, these various combinations cannot naturally happen in nature. All GMO’s are created to defy any herbicide or insecticide it comes in contact with. GMO’s are the origin of genetically modified foods that we see every day.

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...
Genetic modification is a scientific way to enhance crops. The article “Genetically Modified Food” explains this by saying; “A genetically modified (GM) food is a result of recombinant DNA biotechnological procedures that allow the genetic Makeup of an organism to be modified. This can be accomplished by incorporating genes from other organisms of by rearranging genes already present” (Schneider 1). The genes used in the GM plants either comes from other plants of the plant itself. This means nothing going into the plant is from an unnatural source. “Statement by the AAAS Board of Directors On Labeling of Genetically Modified Foods” says, “Modern molecular genetics and the invention of large- scale DNA sequencing methods have fueled rapid advances in our knowledge of how genes work and what they do, permitting the development of new methods that allow the very precise addition of useful traits to crops…” (American Association 1). In traditional breeding there is a guess and check mentality w...

Genetic engineering, sometimes called genetic modification, is the process to alter the structure and nature of genes in humans, plants, and animals (what is genetic engineering). Because DNA is a code that is universal, genes can be manipulated
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 inserting it into another plant. The new genetically modified plant will now have gained drought tolerance as well.

It is evident that the majority of American farmers utilize biotech seeds, because of the risks that the insect resistant and herbicide resistant traits help reduce. GMO's make the life of a farmer much easier as they do not have to worry about rushing to spray herbicides, to keep weeds out, or worrying about insects damaging crops and having to spray pesticides. For instance, Brian Scott a farmer in Indiana, when corn root worms starts indulging on his organic crops, the worms will cause a significant damage before he can react accordingly and eliminate the problem with the use of chemicals. These corn root worms won't affect Scott's insect resistant GMO corn because the pesticide is always in the plant. In addition, the GM corn was created only to harm a small group of insects and this allows for other beneficial insects to survive and assist the crops, since Scott did not have to spray pesticides. Farmers use GM crops mainly because of a reliability issue, not only are biotech plants easier to maintain, but they are less likely to cause a devastating loss. To a point where even insurance companies will provide farmers with lower premiums. Troy Rausch, another Indiana farmer, states "... when you're delayed by a couple weeks by rain like we were this year, the GM traits come in awfully handy for weed control". The GM traits are of much benefit to Rausch as they eliminate the need for him to utilize his time and combat against pesky weeds. The use of GMO's in the agricultural space eliminates many risks that would be common in conventionally bred

Genetically Modified Organisms (GMO) is an organism, such as a plant, animal, or any microorganism who’s had its DNA changed in different ways through genetic engineering that is not natural. It is an organism like every other organism, which produces thousands of proteins, but one or two of them are proteins that were chosen were specifically by humans. It creates unstable combinations of plants, animal, bacterial, and viral genes that do not occur in nature or through traditional crossbreeding methods. Majority of Americans in the US consume nearly 200 pounds of GMOs each year. 90% of US crops are genetically modified.
