Abstract:

CRISPR-Cas is an efficient and practical gene editing tool,which is widely used in genome editing and regulation. Due to its high sensitivity and specificity,the CRISPR-Cas system also plays an important role in nucleic acid detection. It can detect pathogens,analyze single nucleotide polymorphisms(SNPs),and detect genetic mutations. The currently discovered Cas series nuclease tools open the door to the development of new strategies for different types of nucleic acid detection for various purposes. In addition,the CRISPR-Cas system is used in nucleic acid detection. The accuracy and efficiency of the field indirectly promote the progress of basic biology and applied biology research. The article outlines the latest developments and uses of different types of CRISPR-Cas systems that target specific nucleic acid detection,and the corresponding new generation of in vitro detection platforms,which provide new research ideas and theoretical basis for the field of nucleic acid detection.

Key words: gene editing, CRISPR-Cas system, Cas protein nuclease, nucleic acid detection
