Exam points

link a human gene inserted into bacteria with production of the corresponding human protein
identify inserted crop genes for herbicide resistance, insect-pest resistance or improved nutritional quality
State a benefit of a modified crop, such as reduced pesticide use, higher yield or improved nutrition.

choosing cattle to breed so that alleles for high milk yield will be passed on to their offspring

increasing food production by using insecticides to improve quality and yield

inserting genes into crop plants to improve the nutritional qualities of the plant
