The gRNA is a short, synthetic RNA molecule that directs the Cas nuclease to a specific genomic location where editing is desired, enabling precise double-strand DNA breaks. The targeted DNA break triggers the cell’s endogenous repair pathways, which can be harnessed to achieve precise genomic modifications. More stable and precise gRNAs improve the ability to knock out, insert, or modify genes, supporting detailed studies of gene function and the creation of accurate disease models. CDMO partnership is crucialThe advancements in gRNA synthesis and customisation are enhancing the potential of CRISPR-based therapies in medicine. The pegRNA is similar to a standard gRNA but is significantly longer and more complex, often exceeding 150 nucleotides in length.
