CRISPR-CAS9 & DNA FINGER PRINTING

Beyond its revolutionary role in genetic engineering, CRISPR-Cas9 is forging a new path in forensic science through a highly specific DNA detection system. This application leverages the system's core function: the guide RNA's ability to lead the Cas9 protein to a precise DNA sequence. In a forensic context, we can design a guide RNA that is complementary to a specific Short Tandem Repeat (STR) marker, a DNA sequence commonly used for identification.
