Question

which is a disadvantage of using dna technology?
edible vaccines
phytoremediation
herbicide tolerance
gene transfer to nontarget species

Explanation:

• Edible vaccines, phytoremediation, and herbicide tolerance are advantages or applications of DNA technology (edible vaccines for easier delivery, phytoremediation for environmental cleanup, herbicide tolerance for crop protection).
• Gene transfer to nontarget species is a disadvantage as it can disrupt ecosystems, cause unintended genetic changes in non - target organisms, and have unforeseen ecological consequences.

Answer:

D. gene transfer to nontarget species
