1) Genetic engineering or genetic modification is the process of altering an organism’s genetic material for a beneficial purpose. Genetic modification is used to improve the products we obtain from plants and animals making them more nutritious, less-harmful manufacturing processes, and production in large quantities making them less expensive. 2) Gene Therapy- when an absent or faulty gene is replaced by a normal gene in order to treat a disorder or medical disease Plasmid- small circular DNA molecules in the cytoplasm of bacteria, these molecules cut DNA into a recognizable sequences DNA Polymerase Chain (PCR)- technique used to make copies of a certain gene. Biologists particularly use this with tiny genes that are rarely available. Hybridization- crossing different traits to bring the best of organisms into one.
Scientists can modify foods to be healthier, adding fats, proteins and sugars to plants so that consumers with a limited income can have a healthy diet. Genetically modifying organisms will benefit the environment too. With traditional farming, farmers spray their crops with herbicides and insecticides around 4
III. Advantages of Genetically Modified Foods A. Pest, disease, and herbicide resistant B. Drought and salinity tolerant C. Edible by those allergic or intolerant normally Conclusion: To summarize what I have just explained, genetic modification is here. More and more world crops are being modified for resistance to pests, disease, and drought, namely. It appears genetic modification won’t be going away anytime soon, no matter how you personally feel about it. Though before you make a decision, I request, you to do some research about genetic modification, the history behind it and the future of where it is going.
What is the benefit of the modification? Because the GM tomatoes can remain fresh longer they have time to ripen in the sun before picking, resulting in a better tasting tomato! 4. Three advantages of genetically modified foods Longer lasting foods can be more easily transported, Having extra vitamins in food help poor people from becoming malnourished or going blind, and the insecticides inside some genetically modified plants keep farmers from having to spray the whole place down with toxic wastes, and they also 5. A counter argument to one of the disadvantages of genetically modified food Some antibiotics can be transferred to humans and make it harder for us to fight infections, genetically modifying foods could potentially put farmers out of work, and some important insects could be at risk because of the insecticides in foods.
This is quite an efficient method of production and the amount of the PHB polymer yielded is around 30-80% of the dry weight of the micro-organisms used. Even though this method is efficient it is still not quite economically viable as there is the high cost of using the agar solution, petri dishes and the removal of the nitrogen. More recently as this biopolymers potential to society has become more prominent, scientists are trying to develop more efficient and sustainable means to produce it. In 1992 the idea of using genetically modified plants to produce PHB was developed at Michigan State University. By using the genes from two bacteria producing organisms such as Alcaligenes Eutrophus, they could insert them into cress plants with the aim of these plants producing the PHB.
In Partial Fulfillment of the Requirements of Science 9 Submitted by: Macam, Victoria Liz C. Escabarte, Chrystine Hace A. Navarro, Carl Louie T. Abstract: The researchers came up with the problem, “Can vitamins affect the growth of plants?” Many investigations were made regarding this problem yet the researchers wanted to clarify everything and tested the effectiveness of the vitamins with their own eyes. The researchers arrived with this problem because they wanted to know if there is a difference between organic and inorganic fertilizer and human vitamins. Lastly, the researchers wanted to help the farmers in providing a safer and more effective way of having healthy plants. Vitamins are important for the growth of plants. Based on other investigations, vitamins which are made up of organic compounds can help plants grow by providing them with essential nutrients.
Adam Hughes Bio 1106 Lab 57 David Larson Corn Genetics and the Chi-Square Test: Investigating the Genotypes of Corn Plants from Their Phenotypes Abstract: This experiment demonstrates genetics. The study of genetics and inheritance is concerned with understanding the biological properties that are transmitted from parent to offspring. In this laboratory you will study the results of some inheritance crosses similar to those performed by Mendel in his classical experiments on heredity in corn height. In addition to studying the information about such inheritance patterns we will learn how to apply a statistical test to determine the validity of data obtained by such crosses. Corn plants are used to demonstrate the genetics of corn breeding for a monohybrid.
The sweet potato industry, although a high value industry, is becoming increasingly competitive. This underlines the importance of efficiency in minimising the loss of valuable soil. Large amounts of rainfall can result in the loss of soil on cultivated farmland. The loss of soil does not just affect the farmers it also affects the community The aim of the project was to increase awareness of soil health and to develop the best soil management practices for the Cudgen plateau. Figure [ 2 ] Water Way On the Cudgen Plateau, three adjoining landholders implemented soil conservation measures and strategies.
As for the growing end of the spectrum, Pollan then goes on to say that “It (corn) had to adapt itself not just to humans but to their machines” (30). Farmers eventually found inventive ways to mass produce this crop. Planting the crops in such a close proximity created not just more space, but also caused the plants to grow upward. This meant that it was easier for machines to come in and extract the corn, so this ushered in the use of fossil fuel. These machines were created not just to cultivate the land, but to also apply large quantities of chemicals to the crops to prevent insect infestations.
Scientists insert DNA genes from humans, plants, bacteria, viruses and animals into seed DNA to create different traits. By doing this, seeds become resistant to herbicides and pesticides. We feel our products and seeds improve agriculture and lives. What’s my name, you ask? I am Monsanto, a multinational producer of bioengineered and genetically modified seeds and plants.
