  4. The use of natural processes to clean up contaminated environments
Reveal answer Fill a bubble to check yourself
A Correct answer
Explanation

Genetic engineering for bioremediation involves the use of GMOs to introduce or enhance the ability of organisms to degrade or remove pollutants from the environment.

Multiple choice

What are some potential benefits of using GMOs for bioremediation?

  1. Increased efficiency and speed of cleanup

  2. Reduced cost of cleanup

  3. Reduced environmental impact of cleanup

  4. All of the above
