If you answered Yes the first time: What if you knew that detractors fear that GM foods might pose health risks for certain people? Some people, including children, are highly allergic to peanuts and other foods.
Some critics of GM foods feel the possibility exists that those genetically modifying food crops may unintentionally introduce a new allergen.
Given that genes can be introduced from unrelated species -- for example, a fish gene can be put into a plant -- some critics argue that the possibilities of allergies might be greater than with traditionally bred crops.
Another potential hazard to human health is the possibility that bacteria in our guts could pick up antibiotic-resistance genes found in many GM foodstuffs. Food geneticists often add such genes to GM plants as 'markers' to tell them which plants have taken up exotic genes.
If this transfer happens, in principle it could exacerbate the already worrisome spread of disease-causing bacteria that have proven able to withstand our antibiotics. As a medical doctor, I can assure you that no one in the medical profession would attempt to perform experiments on human subjects without their consent.
Such conduct is illegal and unethical. Yet manufacturers of genetically altered foods are exposing us to one of the largest uncontrolled experiments in modern history.
Herbert, pediatric neurologist  "With genetic engineering, familiar foods could become metabolically dangerous or even toxic.
Even if the transgene itself is not dangerous or toxic, it could upset complex biochemical networks and create new bioactive compounds or change the concentrations of those normally present.
In addition, the properties in proteins may change in a new chemical environment because they may fold in new ways. Further, the potential toxic or carcinogenic effects could have substantial latency periods. A Statement by Scientists Concerned About Trends in the New Biotechnology  "Lots and lots of people -- virtually the entire population -- could be exposed to genetically engineered foods, and yet we have only a handful of studies in the peer-reviewed literature addressing their safety.
The question is, do we assume the technology is safe based on an argument that it's just a minor extension of traditional breeding, or do we prove it?
The scientist in me wants to prove it's safe. Margaret Mellon, director of the agricultural and biotechnology program, Union of Concerned Scientists  If you answered No the first time: What if you knew that proponents assert that GM foods will promise many health benefits?
Advocates hold that GM foods will leave traditional crops in the dust. They will have longer shelf life. They will be better for us, with some products already in the works benefiting our waistlines low-calorie sugar beets and oils with lower saturated fat content, for example and others bearing higher nutritional content high-fiber corn and high-starch potatoes.
And they will be safer to eat. GM corn has lower fungal toxin content than non-GM corn, and farmers typically produce GM crops using fewer pesticides, herbicides, and fertilizers. GM foods will have even greater benefits for the world's poor, supporters state.
In developing countries, malnutrition is a grave problem, because people often have to rely on a single staple, such as rice, that on its own doesn't supply sufficient nutrients.
Food scientists hope to genetically modify crops to add vitamins and minerals. One of the most promising is "golden rice," which can stimulate our bodies to generate vitamin A.
In the developing world, vitamin-A deficiency kills two million children each year, and anotherbecome permanently blind. Eventually GM plants will serve as environmentally friendly 'factories' that mass-produce useful substances such as pharmaceuticals. Scientists are hard at work, for instance, trying to genetically add vaccines to tomatoes or bananas.
Traditional vaccines are costly to manufacture and require specialized storage not always available in developing countries.Human hybrids: a closer look at the theory and evidence (fruit flies) that can prevent embryos from developing.
The study points to faster mutation rates found for noncoding DNA, and outlines. Start studying chp Learn vocabulary, terms, and more with flashcards, games, and other study tools.
Search. Create. Some human traits are controlled by a single gene Although Morgan studied fruit flies, the same genetic principles apply to humans. Lab 4: Testing Hypotheses about Patterns of Inheritance For example, eye color in humans is determined by a single gene locus (although other loci can modify its effects).
If the alleles at that locus are homozygous Less common traits (e.g. white eyes in fruit flies) are known as. Gregor Mendel Essay Examples. 44 total results. An Analysis of the Effects of the Human Genome Project on the Moral Standards of Society. 1, words.

Science seldom proceeds in the straightforward logical manner imagined by outsiders. — James D. Watson, The Double Helix: A Personal Account of the Discovery of the Structure of DNA () Genetics is the biology of heredity, and geneticists are the scientists and researchers who study hereditary processes such as the inheritance of traits, distinctive.
Human gene therapy. Gene therapy, In both cases, the genetically modified organism used was a myxoma virus, but for opposite purposes: Fruit flies.
In biological research, transgenic fruit flies (Drosophila melanogaster) are model organisms used to study the .
