B. Frameshift
C. Nonsense
D. Silent


Sagot :

Final answer:

This mutation is a Silent mutation where the amino acid sequence remains unchanged despite the mutation.


Explanation:

This mutation is a Silent mutation. In silent mutations, the alteration of a single nucleotide does not change the amino acid sequence produced by the mRNA, as in this case where the resulting polypeptide remains the same.

Silent mutations occur when the mutation causes no change in the protein product, as the altered codon still codes for the same amino acid. These mutations are considered silent because they are often unnoticed without sequencing the gene or mRNA.
