In genetic engineering, a new gene is added to a random location in a plant’s genome. CRISPR for modification also allows a new gene to be added to a plant, but targets the new gene to a specific location. CRISPR for mutation does not add new DNA. Rather, it makes a small DNA change at a precise location. Mutation breeding uses chemicals or radiation (lightning bolts) to induce several small mutations in the genomes of seeds. Resulting plants are screened for beneficial mutations resulting in desirable traits.
