Can We End World Hunger? Malnutrition and vitamin deficiencies?

Golden rice is genetically modified rice that now contains a large amount of A-vitamins. Or more correctly, the rice contains the element beta-carotene which is converted in the body into Vitamin-A. So when you eat golden rice, you get more vitamin A.

Beta-carotene gives carrots their orange color and is the reason why genetically modified rice is golden. For the golden rice to make beta-carotene three new genes are implanted: two from daffodils and the third from a bacterium

Advantages: •The rice can be considered a particular advantage to poor people in underdeveloped countries. They eat only an extremely limited diet lacking in the essential bodily vitamins. The consequences of this restricted diet causes many people to die or become blind. This is particularly true in areas of Asia, where most of the population live on rice from morning to evening.

Are there any disadvantages?

Artificial selection is the intentional breeding for certain traits, or combinations of traits, over

othersSelective breeding is an example of artificial selection

is the process when a breeder (of animals) develops a cultivated breed over time, and selecting qualities

within individuals of the breed that will be best to pass on to the next generation

HybridizationCrossing dissimilar individuals to bring together the best of both organisms

Example – crossing a disease resistant plant with a food-producing plant

Result – a plant that the farmers need to increase food production

Method Used

Cell transformation Is the genetic alteration of a cell resulting from the uptake and expression of foreign genetic

material (DNA).

Genetic engineering, Recombinant DNA technology

Genetic modification/manipulation (GM)

Gene splicing are all terms that are applied to the direct

manipulation of an organism's genes

Genetic engineering has four main Genetic engineering has four main steps:steps:1.Isolation of the genes of interest from donor 2.Insertion of the genes into a vector 3.Transformation of cells of organism to be modified 4.Tests to isolate genetically modified organism (GMO)

Genetically modified (GM) foods have had their DNA altered through genetic

engineeringGM foods were first put on the market in the early

1990s. The most common modified foods are derived from plants: soybean, corn, canola and cotton

seed oil.

The next GM crops included insect-protected cotton and herbicide-tolerant soybean both of which were commercially released in 1996. GM crops have been widely adopted in the United States.

The first commercially grown genetically modified whole food crop was the Flavr

Savr tomato, which was made more resistant to rotting by Californian

company Calgene

pharming

Gene pharming is a technology that scientists use to alter an animal's own DNA, or to splice in

new DNA, called a transgene, from another

species. Livestock such as cattle, sheep, goats, chickens, rabbits and pigs have already been modified in this way to produce several useful proteins

and drugs.

Cloning is the creation of an organism that is an exact genetic copy of another. This means that

every single bit of DNA is the same between the two

As a family physician, you often treat children who suffer from infectious

diseases that could easily be prevented through vaccination. But

the parents of many of your patients cannot afford the cost of vaccinations.

You hear of a new approach that would reduce the cost to a fraction of its current price: genetically modified

fruits and vegetables that contain various vaccines. By simply eating a banana, a child could be protected against disease - without getting a

shot!
