What is the difference between organisms that have never been genetically modified,and those that have been genetically manipulated?
Question asked by: knowitall
Good question. Organisms that have been genetically modified have had alien DNA injected into them - by alien here we just mean DNA that is foreign to that creature.
So for instance a wheat cell might have some DNA form a firefly injected to make it glow in the dark. So here foreign genes are added in.
With genetic manipulation foreign genes are not added per se, but rather those that are there are mixed or moved around and tweaked, perhaps inactive genes are switched back on for instance to see the effect that they have.
And that is the difference between genetically modified and genetically manipulated.
