Genetic engineering

Genetic engineering is the process of directly modifying an organism's DNA to change its characteristics or introduce new abilities that don't occur naturally. Scientists use specialized tools to cut, copy, and paste genetic material, allowing them to add desirable traits like disease resistance in crops, produce insulin in bacteria, or develop new treatments for genetic disorders. Think of it as precise editing at the molecular level, where scientists can rewrite the instruction manual of life itself to solve problems or create beneficial changes.
