Draw Science.

*So what does it mean to 'design' the recognition domain? Essentially, engineered nucleases use one of two kinds of proteins: either zinc fingers (ZFs) or TAL effectors (TALEs). Both recognize sequences of DNA. By putting several different ZFs or several different TALEs together -- and choosing the right ones -- scientists can recognize very specific sequences (ie. the gene for sickle cell anemia) and then cut it out.
