CRISPR Gene Editing

Definition

CRISPR gene editing is a revolutionary technique that allows scientists to modify DNA within organisms with high precision. It utilizes a system derived from the immune responses of bacteria, where CRISPR stands for Clustered Regularly Interspaced Short Palindromic Repeats, and it works in conjunction with a protein called Cas9 that acts as molecular scissors to cut DNA at specific sites. This technology is pivotal in advancing plant bioinformatics and data analysis by enabling targeted modifications to plant genomes, facilitating genetic improvements, and enhancing our understanding of plant biology.
