One of the most important applications of Molecular Biology is the capacity of manipulation of some organisms genome. This has been used as a very important tool for different purposes like gene therapy.
Beneath this context there are a lot of techniques that are used in a very diverse fields. Within this, we could refer to PCR (Polymerase Chain Reaction), Electrophoresis, etc. Inside all this techniques developed some years ago, we can find one that's a pretty little younger: CRISPR-Cas 9.

Well, ¿What's that? In a simple way (i'ts a very complicated techinque such as the most of Molecular Biology techniques are), it allows to us to alterate and manipulate the genomic expression of an organism (particularly, a bacteria) using some chemical cutters as "molecular scissors" in the DNA. This could (and in the practice it does) allow to develop some anti-viral or pathological bacteria mechanisms at a molecular scale.

I knew of this technique during a molecular biology that I made during the school. In fact, that was the reason why I started to read some papers (in English) and started the scientific literature reading. Since this I improved my reading capacity and now I'm able to, at least, understand what are telling me while I'm talking about science with a scientist or someone who dominates the science.
I guess that this technique, for me as a pharmacist , brings to me the job to develop the molecular tools which are necessary for use CRISPR-Cas 9 and I choose it because is a beautiful way to play to be god. For the humans, this could mean a great advantage in the struggle against the viruses and diseases.
