Clustered Regularly Interspaced Short Palindromic Repeats (CRISPR) are the hallmark of a bacterial defense system that forms the basis for CRISPR/Cas sequence-specific gene targeting technology [1-5].
CRISPR/Cas systems typically consists of two components:
|Component 1||Component 2|
|Cas endonucleases||(s)gRNA Synthesis|
