Genome-wide CRISPR screening is a high-throughput approach that systematically explores gene function across the genome. Using sgRNA libraries, this method enables precise gene knockout, helping identify genes involved in drug resistance, cell viability, and disease progression. Compared to RNAi, CRISPR screening offers greater specificity and efficiency.
