How can you test a food to find out if it contains material derived from a genetically modified organism?
This can be done many ways. One is using an antibody-based test such as the enzyme-linked immunosorbent assay (ELISA), which can detect the proteins that are produced by GM crops. However, the ELISA is not useful for testing foods that is highly processed, because the proteins most likely destroyed & different GM foods produce different proteins. Another way is to use polymerase chain reaction (PCR) to look at the DNA sequence common in GM foods. DNA is more resistant than proteins in processing & can be extracted from heavy processed foods. It is the GMO DNA sequences that's being looked for & tested.
Why is the biotech industry afraid of labeling GMO's?
They are afraid of labeling them because the public is starting to get afraid of the affects of GM foods on their bodies. Labeling them would make the public aware, and since a huge percentage of American foods contain GMOs, businesses could lose tons of money.
What is the GM Family First program?
The GM Family First program is where family members of a GM employee can lease or purchase a new GM vehicle but get it at the price the employee pays. They even will let you combine the discount with most current offers as well!
What are the advantages of GMO plants?
enetically modified foods or biotech foods are foods derived from genetically modified organisms. Genetically modified organisms have had specific changes introduced into their DNA by genetic engineering techniques. These techniques are much more precise[1] than mutagenesis (mutation breeding) where an organism is exposed to radiation or chemicals to create a non-specific but stable change. Other techniques by which humans modify food organisms include selective breeding; plant breeding, and animal breeding, and somaclonal variation. Since genetically modified food has been introduced into supermarkets, there has been much controversy as to whether it is actually safe.
What is density of PA66?
It is 1.07 gm/cc for amorphous type.. and 1.25 gm/cc for crystalline.
How are GM food crops produced?
GM crops are produced much like other crops, except that many that are grown have been genetically engineered to be resistant to herbicides or to produce an insecticide in the plant itself.
What are genetically modified GM organisms and GM foods?
Genetically modified(GM)organisms are those organisms whose DNA, or genetic material has been altered through modern biotechnology whereas GM foods are those from genetically engineered crops.
What are found in GMO foods?
Food normally referred to as GM foods have been genetically engineered in a lab to insert a gene from one species into another species. This gene would be found in GMO foods.
How can Gm food last longer?
The vast majority of GMOs are developed to be resistant to herbicides or to produce a substance in the plant itself that kills insects when eaten. GMO foods, as far as is known, last no longer than non GMO foods.
What effects do genetically engineered crops have on wildlife?
Genetically modified (GM) crops are often engineered so they are resistant to herbicides. This allows the farmer to spray the whole crop with strong herbicides and the GM crops are not affected. It also means that all the flowering broad-leaved weeds that used to grow among the crops are killed. Wild life in the form of birds, bees, butterflies and insects used to come to these weeds and eat the seeds and sup the nectar and eat the leaves. Now they can't. Some species of farmland birds of Western Europe are now only 10% of their numbers 30 years ago, and some have abandoned the farmlands altogether. Populations of bees and butterflies are also much lower in the GM fields.
What are GM crops?
GM stands for genetically modified food. GM foods have been artificially changed by scientists in a laboratory. In the past, plants have been improved by breeding them with other, better plants - a natural process which takes years. But with GM foods, it's done quickly and artificially, and lots of people are worried about it. GM crops are crops that have been altered using genetic engineering techniques, so basically using DNA molecules from different sources and combining them to create a new set of genes which are then transferred into an organism to give that organism a desired trait. Commonly these desired traits cause the GM crop to be tolerant of non-selective herbicides (glyphosate or glufosinate) allowing for easier programs to control weeds (reducing the amount of herbicides needed to be applied). Another desired trait that we see today is the gene that makes the GM crop resistant to insect feeding. There is a great deal of controversy throughout the world concerning genetically modified foods, however no study has ever proven that GM foods are harmful in anyway. We have been eating GM food in the United States for close to 20 years.

When can GM foods be purchased AND where can the GM foods be purchased?
GM food can be found at some of your local markets and at any time of the year but before you buy it i would like to let you know that GM foods can cause allergic reactions and can be poisinous.
Is GM food the way to go if you wish to solve the world's food shortage problems?
Some say it is and others say it is not. Considering that crops engineered to be resistant to herbicides appear to lose that resistance over time, leading to crops that are resistant to other herbicides being created, as well as possible negative effects on species in the soil, and weeds developing super resistance, the pollution issues may outweigh any good effects the crops may have had.
What is genetic modified foods?
Genetically modified food can also be achieved by altering their DNA (or genes) by genetic engineering techniques. This usually involves inserting a gene into the organisms' DNA to create a certain trait. For example, some corn crops have been genetically modified so that they become more resistant to herbicides and insect pests. In most countries Genetically Modified foods (GM) as well as foods containing GM source foods have to be labelled by law, giving consumers the choice to use them or not. Agriculturally speaking the opposite of GM foods are "Organic" crops.

How do farmers grow GM food?
GMO foods are grown very much like non-GMO that are not being grown organically. The big difference is that some of the crops have been engineered to have resistance to herbicides like Round-up. For those crops, the herbicide can be sprayed directly on the crop without killing it; whereas, it cannot be sprayed directly on the non-GMO crops. Other crops have been genetically engineered to produce a substance that kills insects when they eat the plant. In that case, those growing GMO crops theoretically would not need to use pesticides, or at least not as many pesticides, as those who grow non-GMO crops.
