Question

utilizing dna technology
what are some proposed advantages to utilizing dna technology? choose three correct answers.
0% chance for allergies in food products
using genetically modified crops to clean heavy metal pollution
the possibility of edible vaccines through genetically engineered foods
crops engineered for pest resistance

Explanation:

• Using genetically modified crops to clean heavy metal pollution: DNA technology can be used to engineer plants that can absorb and accumulate heavy metals from the soil, a process known as phytoremediation. This helps in cleaning up contaminated soil.
• The possibility of edible vaccines through genetically engineered foods: DNA technology allows for the introduction of genes encoding vaccine - relevant proteins into plants. When these plants are consumed, they can potentially trigger an immune response in the consumer, similar to a traditional vaccine.
• Crops engineered for pest resistance: Through DNA technology (such as inserting genes from Bacillus thuringiensis into crops), crops can be made resistant to pests. This reduces the need for chemical pesticides, which can have negative environmental impacts.

The claim of "0% chance for allergies in food products" is incorrect. Genetic modification can potentially introduce new allergens or alter the expression of existing ones, so a 0% allergy - free guarantee is not possible.

Answer:

• using genetically modified crops to clean heavy metal pollution
• the possibility of edible vaccines through genetically engineered foods
• crops engineered for pest resistance
