CRISPR is the basis of a revolutionary gene editing system. One day, it could make it possible to do everything from resurrect extinct species to develop cures for chronic disease. 这一革命性的基因编辑系统已经席卷了科学界。CRISPR是革命性基因编辑系统的基础。总有一天,它可能使一切成为可能,从复活...
Two gene editing tools—zinc finger nucleases and transcription activator—like effector-based nucleases—have been in use for some time. The newest gene editing tool to be discovered is CRISPR-Cas9. CRISPR stands for Clustered Regularly Interspaced Short Palindromic Repeats, and Cas9 is a ...
Gene editing is a genetic manipulation in which a living organism’s genomic DNA is deleted, inserted, replaced, or modified.
D. It protects the DNA from damage. 相关知识点: 试题来源: 解析 B。解析:文章中明确提到CRISPR - Cas9像一把“分子剪刀”,能精确地定位细胞内特定的DNA序列,一旦定位,Cas9这个酶就会在想要的位置切割DNA,所以它的主要功能是定位并切割特定的DNA序列,B选项正确。反馈 收藏 ...

While regulation and a better understanding of this gene editing tool is needed, the potential benefits of CRISPR cannot be easily overlooked, some of which are already coming to fruition. In 2019, it was used for the first time to treatsickle cell disease and beta-thalassemiain adult patients...
That includes CRISPR and other technologies for targeted gene editing. Over the next decade, gene editing could help humanity overcome some of the biggest and most persistent challenges in global health and development. The technology is making it much easier for scientists to discover better diagnost...
