Quoted: To fix the mutation, the team created a special pre-formed molecule that works like using a pair of scissors to snip directly at the gene. Other methods, without the pre-formed molecule, are like sending scissor parts to the tailor and asking them to put the scissors together before snipping. The procedure is “technically well-done and kind of a tour de force” says Krishanu Saha, a professor of bioengineering at the University of Wisconsin-Madison who was not involved with the study.
