I'm not going into the GMO debate here. I wanted to say "good job!" explaining a very complex matter of generating a GMO to those without biology/biochemistry background. You would need a lot more posts to explain every detail, but this is pretty good. So, good job! :)
I would just add that the genetic engineering field has made considerable progress, some very recently (read about CRISPR-Cas system). However, there is a lot we do not understand about how the cells work, which is why scientists are extra careful when it comes to application which might affect humans or animals. Of course, mistakes can be (and were) made occasionally.
Oh I've used Cas9 in the past. ;)
This is also a blast from the past. I forgot I wrote this. :)
Man I could really have used some formatting lessons back here.
I realized the post was 2 years old, but the subject is still hot and I just had to say something :) I guess a little reminder won't hurt.
Cas9 is amazing, isn't it? When it works on your target sequence, that is. A real game changer for all of us in the lab.
