Final answer:
Genetic engineering can be used to produce plant-based antibodies, where genes encoding desired antibodies are inserted into plants. The usability of these antibodies post-ingestion is subject to further research. Plants such as lettuce and tobacco have been considered for this kind of genetic modification.
Step-by-step explanation:
Plant-Based Antibody Production Project
Genetic engineering of plants to produce antibodies for human use, often referred to as plantibodies, involves several steps. A. To modify a plant's cells, genetic engineers would insert gene sequences that encode the desired antibodies. These genes are typically cloned from animals that produce the antibody and then engineered into plant-compatible sequences.
B. The usability of the antibodies after ingestion depends on various factors such as their stability in the digestive system and the immune system's response to them. While some research suggests that antibodies produced in plants can be effective upon ingestion, more research is needed to confirm this approach's efficiency and safety.
C. Ideal plants for this purpose would be those that are commonly consumed and can be easily and safely transformed genetically. Lettuce and tobacco are among the plants that have been used in research for their potential to produce edible vaccines and antibodies.
