The best source detailing the components used in making GE crops is probably this list at USDA- APHIS.
This site lists all of the GE crops (regulated articles) for which a petition has been submitted, and the status of each petition.
To find component details, select the specific GE crop you’re interested in and click on the arrow link to open up links to detailed documents, including Federal Register notices, the petition itself and usually some other... Read More

I see lots of potential downsides with using the GE corn to produce insulin, from the more complicated transformation procedure, to more difficult extraction/purification, to the possibility (however remote) of food/feed corn admixtures. I was able to come up with no compelling reason to engineer a corn plant to produce insulin, as long as the bacterial system is operating effectively (which, as I understand, it is).

Modern GMOs are developed by teams of experts in different fields, as few individuals have the broad range of skills needed to develop commercialized GMOs alone. Also, different kinds of GMOs are developed for different purposes by teams with differing expertise. For example, a GMO to produce a pharmaceutical product like insulin would not require the same expertise as a GM corn crop with enhanced drought tolerance.
However, the experts typically have college level training in... Read More

Genes — portions of the chemical abbreviated as DNA — have been moved around from one species to another by humans since the 1970s, and by Mother Nature for eons. In every case, the anticipated outcome has been realized. For example, humans have been moving the gene for insulin from humans to bacteria for almost half a century (and now provide insulin for almost all insulin-dependent diabetics). In every case, the recipient bacteria “read” the human insulin gene recipe and make human insulin.... Read More

The pictures from that study conducted by Gilles-Eric Séralini are frightening—and made for sensationalistic media coverage. However, when teams of scientists from around the world looked at the study carefully, they found that the conclusions drawn by Séralini were not credible and that the study itself was seriously flawed and provided no new grounds for concern about GM food. The paper was criticized by public scientific and medical societies worldwide for its faulty... Read More
