Genetic Origins and Interventions of Insulin-Dependant Diabetes Mellit
Diabetes Diabetes is a disorder of metabolism-the way in which your body converts the food you eat into energy. Most of the food you eat is broken down by digestive juices into chemicals, including a simple sugar called glucose. Glucose is your body's main source of energy. After digestion, glucose passes into your bloodstream, where it is available for cells to take in and use or store for later use. In order for your cells

Genetically Engineered Food
Millions of people all over the planet suffer from poverty and starvation. One very interesting but experimental solution to the problem of world hunger is genetically engineered food. The process involves the crossbreeding of crops in a laboratory with species that are not plant like. Say for example, that a scientist crossed a fish and a potato. The diversity of this gene mixture is supposed to give this hybrid crop special characteristics like resistance to

Genetically Engineered Foods - Risk to Humanity
GENETICALLY ENGINEERED FOODS- RISK TO HUMANITY Giant transnational companies are carrying out a dangerous global experiment by introducing large numbers of genetically engineered foods into our diet. Genetic manipulations can result in unanticipated harmful effects, and because genetically engineered foods are not tested sufficiently, this experiment not only jeopardizes the health of individuals, but could also lead to global food shortages and extensive ecological hazards. Due to genetically modified food's unique and unknown nature,

Genetically Modified Foods
Virtually every crop we eat have undergone hundreds of years of genetic modification by farmers and scientist in search of desirable traits. Selective breeding and hybrid strains have contributed immeasurably to farm productivity during this time. Over the past 30 years however, genetic engineering has been revolutionized. While before, a farmer wanting to develop a frost resistant tomato would be able to breed towards one only if the necessary genes were available somewhere in tomatoes
