QIs it true that all corn on the planet is already genetically modified?

Is it true that all corn on the planet is already genetically modified?

AExpert Answer

Corn has been grown by humans for approximately 10,000 years, and its genetics have been heavily modified through breeding and mutation to improve its utility as a crop over this very long period. The modern technique of transgenesis has been used to further improve the agronomic characteristics of corn over the last two decades. Transgenesis has become synonymous with the term “genetically modified” (GM) over this time period, but it is really a misnomer. So all corn on the planet has been genetically modified by human activities, but not all corn has transgenes inserted by the modern technique of transgenesis.

A former response to a similar question answered by Dave Kovalic, Regulatory New Technology Lead at Monsanto, also provides information on scientific advancements and how they [Monsanto] affirm safety prior to targeted vector insertion.   “For context, it is important to recognize that random genome insertions have been naturally occurring in crops over the ~10,000-year history of agriculture.  In some crops, more than 90 percent of the genome consists of these...

In terms of the science behind the technology to create GMOs, scientists have a much better understanding how a transgene is delivered and stably integrated into a chromosome (or genome). Many GMO products, such as Bt corn, were made using Agrobacterium cells to deliver useful trait genes into the plant cells. Scientists were able to dissect the different steps of this natural gene delivery system encoded by Agrobacterium. We now have a good understanding of the interactions between... Read More

Thank you for your questions, we would like to address these individually.   Why are GMOs created if scientists are not aware if it is really harmful? and Are GMOs really safe if you’re mixing to different DNA strands? yes GMOs are safe. In fact, according to this response, “the overwhelming consensus of scientific experts and major scientific authorities around the world, including the World Health Organization, Food and Agriculture Organization of the United Nations, and...
