Genetically modified foods are organisms that have had specific changes introduced into their own dna with genetic engineering gm foods were first put on the market in the early 1990s genetically modified foods are usually plants that have been modified such as soybean, corn, canola and cotton seed oil. Corn corn, also called maize, is native to mexico and has become one of the most widely grown crops in the world there are 142 different events (types) of genetically modified corn, the most of any plant species.
Genetically modified maize is a genetically modified crop specific maize strains have been genetically engineered to express agriculturally-desirable traits , including resistance to pests and to herbicides. Last year only 3 to 4 percent of the sweet corn raised in the united states came from the genetically modified sweet corn seeds syngenta, a global agribusiness company, introduced 15 years ago monsanto hopes to change all that. Genetically modified corn’s allergic reactions can be caused by a number of factors and a person who avoids genetically modified corn may still be at risk let’s say an animal on the farm where genetically modified foods are being grown gets into a gmo corn crop and consumes a large amount. Bt corn: genetically modified corn dna extraction/separation is the first step in the genetic engineering process this is accomplished by taking a sample containing the gene of interest (the bacillus thuringiensis ) and taking it through a series of steps that separate the dna from the other parts of a cell.

Genetically modified corn has dramatically reduced populations of a corn-eating worm pest and put more money in farmers' pockets but paradoxically, most of the financial benefit went to farmers. Genetically modified corn— environmental benefits and risks despite such discord, genetically modified (gm) crops have the fastest adoption rate of any new technology in global agriculture simply because farmers benefit directly from higher yields and lowered production costs.
Thus, it is more accurate to use the term transgenic crop instead of genetically modified crop here, we dispel many of the myths and half-truths surrounding transgenic crops here, we dispel many of the myths and half-truths surrounding transgenic crops. The concept of “genetically modified organisms,” or gmos, has received a large amount of attention in recent years indeed, the relative number of google searches for “gmo” has more than tripled since late 2012 [1. The term genetically modified (gm), as it is commonly used, refers to the transfer of genes between organisms using a series of laboratory techniques for cloning genes, splicing dna segments together, and inserting genes into cells.
