Unless you’ve been sitting in a cave for the last couple of years, you have probably heard about the new great promise of gene therapy: the gene editing CRISPR system. This new addition to the molecular biology toolbox is groundbreaking for what it implies. It does not simply “force in” a healthy copy of whichever mutated version of a gene, but operates over the “sick” copy of the gen in the cell by cutting and replacing the mutated nucleotides for the “healthy” ones.  One of the big advantages of this method is that it avoids integration of extraneous DNA in regions away from the mutation, and there decreasing the chances of inducing tumoral processes.
