Genome editing is a scientific technique that allows researchers to modify an organism's DNA. By making precise changes to the genetic material, scientists can add, remove, or alter specific genes. This technology has applications in various fields, including medicine, agriculture, and biotechnology. One of the most well-known methods of genome editing is CRISPR-Cas9, which uses a guide RNA to target specific DNA sequences. This approach has revolutionized genetic research, enabling advancements in treating genetic disorders, improving crop resilience, and studying gene functions more effectively.
