The use of recombinant DNA technology in agriculture aims to achieve various goals, including:
A. Producing plants with improved food/nutritional properties: Recombinant DNA technology can be used to introduce specific genes into crop plants to enhance their nutritional content, increase yield, improve taste, or provide additional health benefits.
B. Protecting crop plants against a variety of different environmental stresses: By introducing genes from other organisms, crop plants can be made more resistant to various environmental stresses such as drought, extreme temperatures, salinity, and pests. This can help improve crop productivity and reduce losses.
C. Making crop plants poisonous to insect pests: Recombinant DNA technology can be used to introduce genes that produce insecticidal proteins into crop plants, making them toxic to specific insect pests. This approach is commonly used in genetically modified crops like Bt (Bacillus thuringiensis) crops, which produce proteins toxic to certain insect pests while being safe for humans and non-target organisms.
Therefore, all of the choices (A, B, and C) are goals for the use of recombinant DNA technology in agriculture, depending on the specific objectives and applications.
