STALIN [3.7K]

Answer:

" Natural gas does not produce greenhouse gases as other energy sources do."

To restore the wild-type level of activity the alanine would have to mutate to another polar uncharged amino acid. Among the given options, only Asparagine (N) has a similar chemistry to Glutamine.
