(d) They improve the nutritional quality of foods. 19. Most foods derived from genetically modified crops contain: (a) The same number of genes as food produced from conventional crops. (b) The same number of genes as foods produced from hybrid crops. (c) One or two additional genes. (d) (d) Hundreds of additional genes. 20. How long does it take to develop a new genetically modified crop? (a) Twenty years (b) Ten years (c) Five years (d) One…
Appendix Table 2 (By Antonio Ortiz) 34 Abstract For thousands of years people have developed plants and animals with the characteristics they want by selectively breeding the best plants and animals. The need for using genetically modified organisms is simply defined as sheer volume of consumers. In order to feed and provide other non-food products to individuals, current ingredients had to be altered to be able to fit the growing needs of the country.…
What are genetically Modified Foods? Genetically modified foods are foods that have had their DNA altered through genetic engineering3. Genetic engineering involves inserting genes from one species into the DNA of another species. These new genes will result in different traits being expressed in…
GM foods are produced from genetic engineering. Scientists take a certain gene from an organism that is desired and put it into another organism. For example, scientists might take a drought resistant gene from a plant and insert it into a crop, so that crop will not die during a period of low rainfall. There are various ways to add in these desired genes, such as crossbreeding, which has been…

Genetic modified foods can be very beneficial to farmers who have loss crops from pests and insects that eat them. Originally farmers used chemical pesticide annually to kill pests however; they found that consumers would not eat the food as it was a health hazard. Also it had harmed the environment as the pesticide would poison the water supply. By having genetically modifying crops food can be protected from insects and pests. Bacillus thuringiensis(BT) Corn is an example of a genetically modified crop, which contains delta endotoxins and when insects are exposed to this the toxins will paralyse the insect’s digestive system and kill it. Hence GM foods can be very beneficial as the production of agriculture will be less damaged.…
A genetically modified organism is an organism whose DNA or genetic makeup has been modified to code for certain desirable traits("Genetically Modified Foods"). Common genetically modified plants include corn and soy, and common genetically modified animals are fish. Many genetically modified plants are coded to resist bugs, grow faster, and produce bigger fruit, while most GMO animals are coded to grow faster and have better meat. This can help alleviate world hunger, and can also lower the cost of food production.(Calhoun) To determine if the food we selected was genetically modified, we used two biotechnology techniques: PCR and…
Someone out there has probably wondered why their tomatoes which they bought at a supermarket, taste different than the tomatoes at a farmers market. Well to answer that curious person, the tomatoes from the supermarket are most likely Genetically Modified. Genetically Modified foods (GM foods) are organisms in which genetic material (DNA) have been altered in a way that is not natural. Basically they are inserting genes of another species into their DNA, the process is known as biotechnology. 45 percent of corn and 85 percent of soybean are genetically modified. Fulton states that “some 70-90 percent of processed food is genetically modified and has been that way for years” (“Politics Heating Up Over…”). The first GM plant was produced in 1983, an antibiotic resistant tobacco. In 1990 the first GM cotton was produced, from then on scientists and farms have tied to make everything genetically modified. It is important for people to understand what they are eating and how it was made.…
Genetically Modified Foods, sounds like it is helping the world, by increasing yields of crops, and making it possible to grow any type of crop in its unnatural environment. However there is some disadvantages, it is believed that there may be unknown health risks, it could be dangerous to some insects, as the new genes of the crops could be harmful to certain insects like butterflies, which aren’t potentially dangerous to these crops. It could also cause a threat to the environment, due to the fact that it is not a natural way to grow…
Genetically engineered crops are still a very unknown and even in some cases unheard of subject to people globally. This technology, even being such and unknown subject, has quickly and only gaining speed overruns our diets by stating with our most consumed food crops. Genetic material from one organism is inserted in the genetic code of another and by doing this biotechnologist have created vast amounts of different genetically engineered organisms. Organisms such as tomatoes with flounder genes, fish with growth genes, pigs with human growth genes, along with thousands of other plants, animals and insects.…
The food you are eating is killing you. These foods are genetically enhanced to make them last longer taste better, and shield themselves from pests and weeds. Genetically modified foods are in everything, you ate them for breakfast and you will eat them for lunch. You need to learn about these foods to save your family and friends from the terrible effects of these foods. You will learn what these foods are, the bad effects of them, and what will happen if we don't take action and put an end to them.…
Genetically modified foods are becoming more and more used in our community. But, they are not as safe as people presume them to be. Genetically modified foods can cause a big problem in the world, even if it can produce large quantities of foods, it is found that it can cause an allergy to certain foods, many scientists had voted to ban…
Modified and engineered foods are highly debated yet often not clearly understood by the public. It can seem almost impossible to find trustworthy information on GM crops. Studies and scholarly articles can even elicit controversy. Many different terms can be tossed around, which is often confusing to someone not well versed in the vocabulary. We may hear, Genetically Engineered (GE) food or Genetically Modified Food (GMF) and although we may see the terms GM and GE used interchangeably, they are not one in the same. Genetic engineering refers to foods that have had their DNA altered by the insertion of genes from an unrelated species, to introduce new, desirable traits that would not otherwise happen in nature. Genetic…
In 1983 genetically modified food was introduced to the world, and by 1996 it was found on super-market shelves worldwide. It was a huge commercial explosion. Genetically modified food is produced from plants and animals that scientists have been able to modify by changing the gene structure, which can alter foods characteristics. One of the first examples of genetically modified foods is the FlavrSavr tomato; as you know when a tomato ripens, it reddens becomes soft, and naturally rots. Scientists then chemically were able to change the gene that causes this, meaning the tomato can ripen for longer, redden for longer, and rot slower than it naturally would.…
Genetically Modified Crops are made for many different purposes, the main purpose being to create a food able to survive being sprayed with harmful chemicals like pesticides and herbicides. Other purposes are to make food stay fresher for longer, to kill pests, to produce more of the crop and to experiment with taste and quality. The most common foods are maize, cotton, tomatoes, potatoes, corn, canola, soybean and sugar beet(6).…
