CRISPR genes represent a revolutionary technology in the field of genetic engineering. Derived from the immune systems of bacteria, CRISPR genes are composed of short, repetitive DNA sequences interspersed with unique genetic code. Paired with the protein Cas9, CRISPR allows scientists to precisely edit and modify genes within living organisms. This groundbreaking tool has immense potential for applications in medicine, agriculture, and various scientific endeavors. Researchers are using CRISPR gene editing in clinical studies as a new tool that is rapidly growing to treat numerous diseases. Genome editing offers the ability to correct mutations in cystic fibrosis using base editing it changes individual DNA letters or bases relying on the Cas9 enzyme used in the original CRISPR system.
