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

When creating a GMO and adding a gene from another species does the new addition change the genome of the organism by activating or creating new genes?

The term “GMO” typically refers to crops or animals that, through genetic engineering, have had a gene (or a few genes) from a different species inserted into their genome. So yes, by design, to improve a crop or animal with genetic engineering, the genome of the new, GE variety has been changed by the addition of new genes(s). Your question also asks about whether inserting the new gene(s) will “…activate genes…” Some traits in... Read More

The first use of recombinant DNA technology, was created by Cohen and Boyer in 1972 with E.coli in 1972 and this article explains this advancement in biotechnology in greater detail. Here is an excerpt: “Their experiments dramatically demonstrated the potential impact of DNA recombinant engineering on medicine and pharmacology, industry and agriculture.” Recombinant insulin was the first commercial product derived from genetic engineering techniques created in 1976 by the...

A gene with a desirable trait can be moved from one organism to another organism as a means to change it. The traditional way is through selective breeding, which is slow, time consuming, inefficient, and transfers more than one gene, so other unexpected and unwanted traits can cause problems. But genes also can be moved in a laboratory, resulting in what has been called a genetically modified (“transgenic”) organism (GMO). GM technology moves only one gene, eliminating other,... Read More
