Broccoli is a vegetable plant that is grown as a crop in many parts of the world. Broccoli is susceptible to a disease called clubroot. Genetic engineering can be used to produce clubroot-resistant varieties of broccoli. Genetic engineering involves inserting resistance genes into the cells of the broccoli plants. The resistance genes were obtained from linseed plants. Scientists can use DNA profiling to identify the broccoli plants that have been successfully genetically engineered. After PCR, gel electrophoresis was used to separate the DNA fragments. Which type of enzyme is used to produce DNA fragments? (1)
