Mutation and hybridisation are widely used in fiction, starting in the 19th century with science fiction works such as Mary Shelley's novel Frankenstein and H.
When gene transfer occurs, the resulting organism is called transgenic or a GMO genetically modified organism. Genetic engineering is different from traditional cross breeding, where genes can only be exchanged between closely related species.
With genetic engineering, genes from completely different species can be inserted into one another. For example, scientists in Taiwan have successfully inserted jellyfish genes into pigs in order to make them glow in the dark. F What are genes?
All life is made up of one or more cells. Each cell contains a nucleus, and inside each nucleus are strings of molecules called DNA deoxyribonucleic acid. Each strand of DNA is divided into small sections called genes. These genes contain a unique set of instructions that determine how the organism grows, develops, looks, and lives.
During genetic engineering processes, specific genes are removed from one organism and inserted into another plant or animal, thus transferring specific traits. GE Crops Nearly million acres of farmland worldwide are now used to grow GE crops such as cotton, corn, soybeans and rice.
GE proponents claim genetically engineered crops use fewer pesticides than non-GE crops, when in reality GE plants can require even more chemicals.
F This is because weeds become resistant to pesticides, leading farmers to spray even more on their crops. F This pollutes the environment, exposes food to higher levels of toxins, and creates greater safety concerns for farmers and farm workers.
Some GE crops are actually classified as pesticides. For instance, the New Leaf potato, which has since been taken off grocery shelves, was genetically engineered to produce the Bt Bacillus thuringiensis toxin in order to kill any pests that attempted to eat it.
Because of this, safety testing for these potatoes was not as rigorous as with food, since the EPA regulations had never anticipated that people would intentionally consume pesticides as food.
F Adequate research has not yet been carried out to identify the effects of eating animals that have been fed genetically engineered grain, nor have sufficient studies been conducted on the effects of directly consuming genetically engineered crops like corn and soy. Yet despite our lack of knowledge, GE crops are widely used throughout the world as both human and animal food.
GE Animals Scientists are currently working on ways to genetically engineer farm animals. F Genetic engineering experiments on animals do, however, pose potential risks to food safety and the environment.
Inscientists at the University of Illinois were conducting an experiment that involved inserting cow genes into female pigs in order to increase their milk production.
They also inserted a synthetic gene to make milk digestion easier for the piglets. Although the experimental pigs were supposed to be destroyed, as instructed by the FDA, offspring of the experimental pigs were sold to slaughterhouses, where they were processed and sent to grocery stores as pork chops, sausage, and bacon.
F University of Illinois representatives claimed that the piglets did not inherit the genetic modifications made to their mothers, but there was still a clear risk to the people who purchased products made from the piglets.
Since no genetically engineered animal products have ever been approved by the FDA, the pork products that reached supermarket shelves were technically illegal for human consumption. As a result of the accident, the FDA sent letters in May to all land-grant universities, reminding researchers that their work "may require" licensing under the animal drug law.Genetics is a branch of biology concerned with the study of genes, genetic variation, and heredity in living organisms..
Gregor Mendel, a scientist and Augustinian friar, discovered genetics in the late leslutinsduphoenix.com studied "trait inheritance", patterns in the way traits are handed down from parents to offspring.
He observed that organisms (pea plants) inherit traits by way of discrete. Smoking cannabis increases risk of depression in the case of genetic vulnerability, study finds Date: October 13, Source: Radboud University Nijmegen.
