CRISPR (Clustered Regularly Interspaced Short Palindromic Repeats) is a revolutionary gene-editing technology that allows scientists to edit parts of the genome by removing, adding, or altering sections of the DNA sequence. It is simpler, more efficient, and more versatile than earlier forms of genetic editing, making it a powerful tool for genetic research and applications. CRISPR has various applications, including treating and preventing the spread of diseases, improving crops, and potentially correcting genetic defects. The technology is based on a natural system used by bacteria to protect against viruses, adapted for use in other organisms.
