CRISPR technology is a powerful tool that lets scientists edit DNA with precision. It uses a system found in bacteria that acts like molecular scissors to cut DNA at specific places. The key part is a protein called Cas9, which is guided by a small piece of RNA to the exact spot on the DNA where editing is needed.

Scientists can use CRISPR to do different things with genes. They can turn off a gene, change its instructions, or even add new parts. This ability has huge potential in many areas. In agriculture, CRISPR can help create crops that resist diseases or grow better in harsh conditions. In medicine, it could treat genetic diseases by fixing faulty genes.

CRISPR is easier and faster than older methods of genetic editing, making research and applications more accessible. However, there are important ethical questions, especially regarding editing genes in humans. This technology continues to evolve, promising new ways to improve crops, cure diseases, and understand genetic disorders better.
