The third step is to insert the DNA into the organism which the scientist wants to modify. Scientists use a gene gun to put the new genes into the organism. These guns aren’t meant for shooting someone to grow an extra arm, though. A gene gun shoots out tiny metal particles that are covered in DNA, which ends up inside the chosen organism and modifies it. This shows how the scientists insert DNA into different organisms.
Finally, the last step is to grow the organism out. For the DNA to take place, the plant/animal needs to grow and reproduce those genes so they actually show up in the organism.
While it is a very slow process, farmers still use selective breeding to improve their crops. Since GMOs have a very large potential, humanity can solve many problems by creating GMOs. Some popular genes that scientists would like to include in plants are that they could be resistant to insects and viruses, and make it so they have more vitamins and minerals.
Safety of GMOs
But the main problem is the dispute about if GMOs are safe, or if we shouldn’t mess with nature. Kevin Klatt, a student with a PhD in the molecular nutrition program says, “We got ruby red grapefruits through natural mutation, yet few are questioning the safety of all the random genetic changes that went into their development.” This shows that nature still had a much greater influence on how some fruits and animals turned out to be than what we intend on changing because genetic modifications can happen naturally.
Alison Van Eenennaam, a specialist in biotechnology with a PhD says,"DNA has always been part of our diet, and it's digested in your stomach along with the rest of your food, there is not some evil trace of poison." This is something that most people doubt about GMOs. They think that the added genes might make the food dangerous and that we don’t need to change anything, but others say that we need to because there are problems that need fixing and GMOs are a solution.
Since genetic engineering is something pretty new to humanity, the human race in general, some people are still scared of it. They also think that changing nature isn’t something that we should do. Scientists still have to do a lot of research before changing an organism.
Stephen MacDonald, who has a PhD and is a specialist in biotechnology says, “I don’t think they are dangerous per se, but I don’t trust the data that says they are entirely safe either.” This says that GMOs are mostly safe, but there could be some that are actually dangerous. This also shows the other side of the debate on GMOs. The side that doesn’t want genetic engineering. What do you think should happen?
In conclusion, genetic engineering takes a lot of steps and a lot of research to do. It takes some time, but it is much much faster than selective breeding. It could have a great impact compared to selective breeding for the better, or for the worse. But the topic is very controversial, which means it is argued over a lot, and we can’t just change nature as it is. We will just have to wait and see how these genetic modifications will impact the world as it is today.
