Genetically modified Organisms

It's not jellyfish DNA though. Or at least, I've not heard of it (source?)

Usually it's just custom-made genes which are cultured in bacteria (like is done for manufacture of insulin) and then extracted into plants, which then breed.

One example is jellyfish DNA in tomatoes, we talked about in class.

When it tests bad, then it gets pulled.

That should be true for a lot more things than it is. When people or companies have been doing the same thing for decades, or centuries, or millennia, they tend to want to stick with it, even if it's bad.

But the truth is, everything is potentially dangerous. The question is, is it worth the risk, and the risk is always changing because of new discoveries.
