For which codon(s) of isoleucine could a single base change account for an amino acid change to methionine? a. auc b. auu c. aua d. aug e. none of these codons

option A and B (AUC & AUU)

Explanation:

Codons of isoleucine are AUC and AUU, while codons of methionine are AUA and AUG.

Therefore, a single base change in cytosine of "AUC" could yeild any of methionine codons, also a single base change in AUU will do the same.

This single base change is refers to as point mutation, and it is generally reversible.

stimulus is a change in the environment that causes an organism to react. the response is the reaction to the stimulus. some examples of stimuli for zebras are drought, to many predators, and bad feeding grounds such as dead grass or plants. zebras respond to stimuli just like all other living organisms
