摘要:
CRISPR/Cas系统(Clustered regularly interspaced short palindromic repeats/CRISPR-associated)是广泛存在于细菌及古生菌中的，由细菌体长期进化而形成的，能够降解入侵病毒或噬菌体DNA的适应性免疫系统。由于CRISPR/Cas的Ⅱ型系统比较简单，因此成为目前应用最为广泛的方法。本文主要介绍了CRISPR/Cas系统的基本结构、作用原理、技术特点、研究进展以及该技术可能的应用前景等方面内容。CRISPR/Cas (Clustered regularly interspaced short palindromic repeats/CRISPR-associated) refers to an adaptive immune system that is gained from the long-term evolution of the organism which is widespread in bacteria and archaea. The system is able to degrade the invading virus or phage DNA. TypeⅡ of CRISPR/Cas system has become the most popular method due to its simplicity. This paper summarizes the basic structure, principle, technical characteristics and the progress of CRISPR/Cas, as well as the application prospect of the technology.
