A Review from Code to Cure-Crispr/Cas9 in Modern Therapeutics

Clustered frequently interspaced short palindromic repeats (CRISPR) and CRISPR-associated protein 9 (Cas9) gene-editing skill is a promising future tool for giving diseases by efficiently and precisely stopping genes that cause diseases or permanently correcting harmful base mutations. CRISPR-Cas9 represents a ground breaking and highly effective genome editing technology that allows for exact and targeted alterations of DNA sequences within living organisms. Originating from a natural defence mechanism utilized by bacteria, the CRISPR-Cas9 system has gained immense popularity in molecular biology because of its user-friendly nature, programmability, and versatility. The introduction of CRISPR-Cas9 technology signifies a remarkable advancement in gene editing, providing a highly effective, cost-efficient, and programmable method for precise genomic alterations. In contrast to previous genome editing tools like zinc finger nucleases (ZFNs) and transcription activator-like effector nucleases (TALENs), CRISPR-Cas9 is distinguished by its straightforward design and capacity to target nearly any genomic site with high accuracy. This system permits the creation of targeted double-stranded breaks at specified DNA locations, enabling gene knockout, correction of harmful mutations, or the insertion of therapeutic genes through the body's inherent DNA repair mechanisms. Its potential applications are vast, encompassing disease modelling, functional genomics, therapeutic gene modification, and enhancements in agricultural traits.
