新的基因编辑技术问世,这回编辑RNA
-
This story was written by Matthew Herper and Ellie Kincaid. Researchers have invented two new techniques that expand the ability of human beings to edit the genetic code of living things, potentially paving the way for new medical and agricultural applications. The techniques both build on the discovery of CRISPR, a bacterial immune system that biologists have hacked into a gene-editing tool. One, published in Nature, allows the editing of single-letter DNA misspellings in genes, a major cause of illness, to be accomplished far more easily and efficiently. A second discovery, published in Science, uses a new CRISPR enzyme to edit not only DNA but also RNA, the chemical messenger that living things
