No, that is not correct. Both processes happen the same way. And saying that one causes random unknown mutations is completely false.

The DNA in a genome is made up of little chemical building blocks, abbreviated as A, C, T, and G. When scientists successfully decode or "Sequence" an organism's genome, they essentially have a complete blueprint of how each of the little A, C, T, and G building blocks are aligned in the genome. We can then introduce different DNA into the genome, because we know where to put it. We do it in the same chemical manner as what happens in nature. Just with more precision because we only introduce the individual genes we select. Being able to select only the genes we want actually allows for much more control over what traits are passed, compared to normal cross breeding in the field. Normal cross breeding in the field can actually pass traits that are unwanted. Not so with GMOs, we only introduce what we want.

So the processes happen the same way. There's nothing unknown or random about it. Quite the opposite. We wouldn't be doing so if there was a chance of something random or unknown occurring which would have potential negative effects. That's just not the way agro biology works. And this process is tested and regulated to the fullest extent possible.

There are two techniques for creating GMOs. One technique uses an agrobacterium that can insert the new trait into the plant genome using its normal cellular machinery. Or, we use what we call a “Gene gun” to shoot gold or platinum beads, which are coated with the DNA particles you want to insert, directly into the plant cell genome.

Breeders can cross their crop with a wild relative or crop relative to bring in a new trait—like disease resistance. After a series of genetic selections, we know we’ve moved that trait when we see the crop become disease resistant. But, we don’t know what other parts of that relative have also become integrated into the crop.

With the GMO approach, we can be more precise by putting in just that one defined piece of DNA we want without changing other genetic material. It also provides greater versatility, allowing you to capture and insert a gene from a plant, animal or bacterium that would be incapable of naturally crossing with the crop.

Both methods happen the same way, with foreign DNA being introduced, and chemically absorbed into the existing genome. There's nothing magical that separates the process that happens in nature with the process carried out by biologists. Biologists simply do the same thing with more control over the process.

This isn't Toxic Avenger or TMNT green goo type of Hollywood science....
