Depending on what exactly you mean, there arguably are no crops that are NOT genetically modified. Farmers have been breeding crops for thousands of years, and chemicals which alter a plant's DNA were stumbled upon and used before knowledge of exactly how they worked was available.

But I'll assume you're referring to a stricter definition of genetic engineering, as in when specific genes are intentionally added or removed. Most of these foods are not given new species names, as such a slight change doesn't prevent them from reproducing with non-modified crops (part of the problem in getting them accepted, actually!)... instead they usually just have brand names.

One of the most infamous ones was 'Starlink corn'. It's notoriety stems from spreading into the general food supply before gaining FDA approval and triggering a massive recall of just about every product made from corn. Link 1 is a list of largely uninteresting names of some of the GM crops, such as 'MonsantoYieldGard Plus' and 'YieldGard VT™ Rootworm/RR2'.

One of the best-known medicine produced by genetic engineering is actually insulin. Extracting it from animals was difficult and expensive at best, but for a long time scientists didn't even know the exact structure of this hormone, much less were able to make it themselves.

In 1982 insulin because the first genetically engineered medicine ever produced when Genentech spliced the gene into the e.coli bacterium. They could then easily culture huge vats of bacteria and just skim the insulin out of the fluid baths. This was not only cheaper and more productive, but eliminated the risk of transmitting diseases (such as mad cow disease) from animals to humans. Nowadays, bovine insulin is by far the exception rather than the rule.

Later, a company spliced those genes into goats so they could produce human insulin in their milk. Though this hasn't to my knowledge become widespread, it would be by far the cheapest method of producing the drug yet - essentially turning grass into valuable medicine. This is part of the reason why researchers at the Roslin institute were so interested in being able to clone animals.

Other drugs that have been produced in this way (and the diseases they treat) include alpha-1-antitrypsin (emphysema), lactoferrin (septicaemia), and some a monoclonal ntibodies (cancer). As well as goat, chickens are a common target (eggs are rich in proteins) as well as cattle.

Hope that helps!

confident, because of the fact i think human beings could be waiting to make an cautioned decision in the meals they consume. i think the furor over GM vegetation has been blown way out of share and that there is particularly some undesirable technological information obtainable, however the jury continues to be out on particularly some those issues and lots greater effective to ere on the fringe of warning than to have well-being problems look years from now or in the subsequent era. As for the rant from the no longer so top top Winger, modifying genes in the lab is a thoroughly diverse game than breeding for characteristics. yet i think whether that's good for good sized employer we could continuously all merely duck our heads and say confident sir. luckily we've a president and quite a few different contributors of congress who're dedicated to creating our meals safer.
