what is "genetic manipulation" mean?

Question

Can someone please explain what does "genetic manipulation" mean ??

genetic maipulation of food?

Answer 1

There is a gene code for each living thing. It was "broken," or understood, recently so that we can now change or rearrange the codes. First, if some living thing is not working correctly, you can fix the wrong code in it so that it will return to what it was supposed to be doing. For example, if someone has diabetes, it is usually due to the pancreas not working properly. We can now go in with new directions, in effect changing the code, so that the person can grow a new working pancreas, thus no longer being a diabetic. In plants, the manipulations can be for many reasons. To make the plant live longer, be more resistant to weather or attack, to have a longer shelf life, to be a different color, etc. To accomplish this, scientists can change the code in the plant, most often doing this by adding a code from another plant, or even animal. Some strawberries have fish genes in them! I don't remember what the fish genes do, but it probably to make the berries last longer. Hope that helps. Click on the link below for more details

Answer 2

All living things are governed by a pattern of DNA comrised of ATGC (adenine, thymine, guanine, and cytosine respectively) in varying sequences. These sequences are converted into amino acid sequences which fold into proteins. These proteins control organisms by aiding in chemical reactions and basically every aspect of life. Genetic manipulation is the insertion of a sequence of DNA into an organism so it expresses some protein. For example, we can cause bacteria to glow in the dark by putting a jellyfish gene in their DNA. The bacteria have no jellyfish charcteristcs besides glowing in the dark. That is, it is a discrete change (or addition) of one single protein or occasionally some accompanying ones. Gentic manipulation of food generally gives the food 'better' characteristcs. For example, scientists have been able to put a fish gene in some plants that prevents them from freezing. Again, the plants have no fish charcteristcs besides not freezing, and they in no way should taste 'fishy.'
