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

The answer is D. Gene transfer to non-target species.

Explanation:

Using DNA technology we have made several genetically modified crops called GM crops. But sometimes the transgenic trait or gene may effect the non-target species. For example Bt-crops were found damaging the soil health. These pest resistant Bt-crops release Bt toxin near the soil root zones. High levels of Bt toxin can affect the health of soil as well as the soil insects. Hence GM crops must be monitored for the effects on non-target species.
