CRISPR Explained: Fixing DNA Mistakes

How could CRISPR help cure diseases? Feng Zhang, Professor of Biological Engineering at MIT, describes how CRISPR works like a search box for DNA. Using matching RNA proteins, it can find specific spots on the DNA where a gene needs to be edited or repaired. Through this method, it might be possible to go into the human genome and fix the genes that cause sickle cell disease, blindness, or neurodegeneration!
