Genetic modification is like being a chef and changing a recipe to make it taste better. In genes, which are like recipes for making things in our body, scientists can make changes that will make plants or animals better for us to eat or grow bigger and stronger.
Just like when a chef adds an ingredient to a recipe, genetic modification means that scientists add, remove, or change certain parts of the genes of a plant or animal to make it better in some way, like making it more resistant to bugs or increasing its nutritional value.
But scientists don't just randomly change genes. They use a lot of care and testing to make sure any changes to the genes will be safe and have the desired effect, making it better for people, animals, or the environment.
Overall, genetic modification is a special way of changing how plants and animals grow to make them better for us to eat and use, just like a chef making a recipe tastier.
