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.

when a reversible reaction is occurring in both directions at the same rate; the products and reactants do not change in concentration. a chemical reaction where the compound is broken into its constituent parts.

colors do exist. the color of the sky is actually violet; humans percieve the color of the sky as blue.
