DNA modification refers to the process of altering the genetic material within an organism's cells. This can involve adding, removing, or changing specific sequences of DNA to achieve desired traits or characteristics. Techniques such as CRISPR and gene editing allow scientists to make precise changes, which can be used in research, agriculture, and medicine. The implications of DNA modification are significant, as it can lead to advancements in treating genetic disorders, improving crop resilience, and even creating genetically modified organisms (GMOs). However, ethical considerations and potential risks are also important topics of discussion in the field of genetic engineering.
