Which substitution mutation has the potential to cause more damage? a) substitution of 3rd n-base to go from aac to aaa b) substitution of 3rd n-base to go from auu to auc c) substitution of 3rd n-base to go from agu to agc

The answer is letter A. substitution of 3rd N-base to go from AUU to AUC. Substitution mutations are a type of mutation in which a single nucleotide is substituted with a different nucleotide.
