Introduction Over the past two weeks, I have seen the responses to my blog post and the posts of others. I see a lot of confusion on the techniques, results, safety, ethics and current application of GMOs. However, I am well aware that I do not know everything. Let's look at various aspects of GMOs and learn together. What I want to do is to look at the entire process of GMOs. In this post, we will focus on what the concept is. What is DNA? How does it work? Can we use that for agriculture and other things? In the next post, we will look at the techniques necessary to realise that concept. This will introduce a striking difference, as a revolution towards a new and fancy technique called CRISPR/Cas9 has just taken place. When we know how they are made, we can look at what we are currently using them for. Can we see how the technique has been applied currently? Of course, after looking at the past and present we will move on to the future. What can we use them for?
