So, when virus inject their DNA into a cell, and someone doesn’t have an immune system, the virus would usually take over the cell and be inserted into the genome, slowly killing the entire cell. The idea with CRISPR is that proteins are transcribed and translated by the Cas system, in addition to Cas making the spacer DNA transcribe special crispr RNA. The RNA fits into the protein and together they break apart the viral DNA and stop the infection before it has even begun. It is another issue if the genome doesn’t contain the right spacer that matches. In this situation, the cas system create a different type of protein, which takes the DNA, breaks it apart and copies it into the crispr system as a new spacer. All the spacers that are in the genome are unique, because they contain the “history” of previous infections, so it will keep us from being infected by the same virus. Now, this CRISPR system works the same way in everyone who has an immune system, but scientist have discovered a way to use the system to make changes in the genome however they
