Question

Please help me with this​

Answer 1

Answer:

C. One amino acid would change due to a substitution.

Explanation:

The amino acid sequences before and after the mutation are given at the top. The one on the left has the codon CAG while the one on the right has the codon CGG. The rest of the sequences are identical to eachother. This is a subsitution mutation, as only one letter changed.

Using the codon chart, you can see that CAG would make the amino acid Glutamine, while CGG would make the amino acid Arginine. Therefore, the answer is C.
