How do scientist genitically modify food?

Question

i am doing a brouchure on genitically modifing foods and one of the things i have to put in it is how do you genitically modify a kiwi?

Answer 1

They spray the foods with poisons when they grow it and reprodue the plants that can survive the poisons that kill most of the other plants of all types and pests, some of the crop can live when most gets poisoned, they geneically reproduce those ones so that the foods can ook great no matter how much toxins are in them.

perhaps montesanto can help you with toxics and genetics, their crops look awesome

Answer 2

That depends.

Some "genetically modified foods" are bred to be that way. So in that case, crop scientists have bred into crops the traits that they believe will improve production, disease resistance, nutrition etc. This method has been around for 100s (actually 1000s of years) and should not represent any threat to people.

Alternatively, scientists can "transform" genes in plants or animals in a laboratory. This method can be a bit bizarre because unlike breeding, the genes can come from anywhere. For example, this could include putting a fish gene in a radish plant. This method has caused the most controversy (aka "Frankenfoods").

Try the websites below for more information regarding gene transformation.

And by the way, GMO foods weren't created to harm people...they were usually developed to improve food production (not a bad thing in a world where many people still face starvation). The question is....are GMO foods still safe to eat?

Answer 3

Genetically modified foods (GM foods or GMF) offer a way to quickly improve crop characteristics such as yield, pest resistance, or herbicide tolerance, often to a degree not possible with traditional methods. Further, GM crops can be manipulated to produce completely artificial substances, from the precursors to plastics to consumable vaccines.

The techniques of modern genetics have made possible the direct manipulation of the genetic makeup of organisms.In agriculture, genetic engineering allows simple genetic traits to be transferred to crop plants from wild relatives, other distantly related plants, or virtually any other organism.

Recombinant DNA technology thus has brought a new precision to the process of crop development, which traditionally selects desired traits through crosses between crops and their wild relatives (a laborious and relatively imprecise method).

Genetic modification can be used in many ways to control a variety of traits of plants, and the consequences of one manipulation may be completely different from another based on the traits modified.

Although "biotechnology" and "genetic modification" commonly are used interchangeably, GM is a special set of technologies that alter the genetic makeup of such living organisms as animals, plants, or bacteria. Biotechnology, a more general term, refers to using living organisms or their components, such as enzymes, to make products that include wine, cheese, beer, and yogurt.
Combining genes from different organisms is known as recombinant DNA technology, and the resulting organism is said to be "genetically modified," "genetically engineered," or "transgenic." GM products (current or in the pipeline) include medicines and vaccines, foods and food ingredients, feeds, and fibers.

Answer 4

particular. in case you substitute nutrition to contain genes which produce risky gene products. of course, that is a very stupid element to do. as a consequence, you may desire (and help make certain) that genetic modification of nutrition is monitored to make certain that companies, that have income in innovations particularly than public welfare, do no longer, in fact, do something stupid. of course, they have (companies have) already produced genetically changed seeds which produce plant life which at the instant cannot reproduce, with the intention that farmers could purchase new seeds each and every season. I evaluate this unethical and risky interior the severe, and that i think of that the widespread public could have criminal recourse against such companies. yet that's with regard to the only risky consequence of genetically changed meals that i think of is in all probability to take place, a minimum of interior the close to destiny.
