CRISPR is a groundbreaking gene-editing technology that allows scientists to change DNA with speed and precision. Adapted from a natural defense system found in bacteria, CRISPR uses a guide RNA to lead an enzyme such as Cas9 to a specific spot in the genome, where it cuts the DNA so it can be repaired, disabled, or rewritten. This ability makes CRISPR useful for studying genes, developing treatments for genetic diseases, engineering crops that are more resilient, and creating new tools in biote
