Gene modification is a scientific process that involves altering the DNA of an organism. This can be done to enhance certain traits, such as making crops more resistant to pests or improving the nutritional value of food. By changing specific genes, scientists can help create plants and animals that are better suited for our needs, which can lead to increased food production and sustainability. One common method of gene modification is called CRISPR, which allows researchers to edit genes with precision. This technology has opened up new possibilities in medicine, agriculture, and environmental conservation, making it easier to tackle challenges like disease and climate change.
