Crispr: segments of prokaryotic DNA containing short, repetitive base sequences.
Crispr is used to genetically engineer an organism with a perfect genetic makeup.
I don't think it should be used because of the various risks that are going into it. It isn't worth the risk of losing a child. It is a relatively new discovery and not much data about the success of it has been recorded so using it would be a mistake in my opinion and the risk is just too high.
