　　If you could change your child's DNA in the future to protect them against diseases, would you? It could be possible because of technology known as CRISPR-Cas, or just CRISPR.

　　CRISPR involves a piece of RNA, a chemical messenger, designed to work on one part of DNA;it also uses an enzyme (酶) that can take unwanted genes out and put new ones in, according to The Economist. There are other ways of editing DNA, but CRISPR will do it very simply, quickly, and exactly.

The use of CRISPR could mean that cures are developed for everything from Alzheimer's to cancer to HIV.By allowing doctors to put just the right cancer-killing genes into a patient's immune system, the technology could help greatly.
