Food quality is improved because there is less fungal infection, insect damage and residual pesticide. In conclusion to the topic of Genetically Modified Organisms, there is still much to learn, more to research and more to understand. There will be two sides to what is happening how it is affecting and who it is affecting. Scientist will need to do more research to learn the positives and negatives of this process and why do we need to do this. Who will benefit from doing this?…
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…
Modern bioengineering is ‘transgenic’ which means that scientists are swopping genes among species that would never naturally combine. A good example is found in a strawberry. In cold climates, to stop the strawberry from freezing before it is fully mature, scientists are implanting an “antifreeze” gene that comes from the blood of an Antarctic fish. http://lifeofplant.blogspot.co.za/2011/03/legumes.html By scientist’s experimenting across different species, they have produced some amazing things, like organically grown plastics, cancer-preventing proteins, cotton that grows in a variety of colours and tobacco that glows in the dark when being eaten by insects.…
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.…
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…

There are many pros and cons for GM foods, which is why there is a debate whether people should have the choice to eat them or not. Some of the negative portions of genetically modified foods like how harmful they could…
Just about every grain, legume, vegetable and fruit have already been genetically altered in the laboratories, along with many organisms that are used either directly as food, or in production. Just a few examples of genetically modified crops are: Maize, potatoes, soybean, yeasts, herbicide and pesticide resistant crops and modified food additives and enzymes. Even though the effects of genetically modified food will have both positive and negative impacts on the human population, they will impact every person differently.…
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…
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…
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.…
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…
What are the current benefits of having foods made from genetically modified crops? (b) (a) They improve farm profitability and make some farmers’ jobs easier. (b) They allow farmers to greatly increase the amount of crops produced. (c) They improve convenience for consumers, e.g. by creating foods with longer shelf lives. (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…
There are some foods that cause allergy to people when consumed. By modifying the DNA system of these foods, the properties causing these allergies are eliminated successfully. Another positive result of the genetically modified tomatoes is that they will last over a month longer than naturally grown tomatoes. Though the seeds of genetically modified foods are quite expensive, the total cost of production is said to be lesser than the production of naturally grown crops. The main reason for this is that these foods have natural resistance towards pests and insects and so not much pesticides and insecticides have to be sprayed on them. This reduces the necessity of exposing genetically modified crops to harmful pesticides and insecticides, making these foods free from chemicals and environment friendly as well. These are the main reasons that the genetically modified tomatoes would cause positive effects in the…
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.…
