Abstract
CRISPR-Cas9 (clustered, regularly interspaced, short palindromic repeats-associated protein 9) refers to a site-specific method of gene manipulation at the genome level. CRISPR was first discovered in bacteria and archaea as small segments of DNA inserted into CRISPR arrays, which are recognized as an adaptive immune system mechanism to defend against viruses and plasmids. Since the pioneering work on CRISPR sequences in the 1980s, CRISPR-Cas9, which was adapted from the naturally occurring system, has been widely used in gene function research and genetic engineering. CRISPR-based genome editing made a huge leap forward in 2013 when studies on efficient gene manipulation in mammalian cells were reported. CRISPR-Cas9 editing is highly versatile because of its simple operation, specificity, and high efficiency in modifying target genes. Theoretically, any genome sequence can be edited by this system, which has advanced applications ranging from research in basic biology to biotechnology and medicine.
