The correct response is: **The mutated sequence still codes for the same amino acid.**
This refers to the concept of "silent mutations," where a change in the DNA sequence does not alter the amino acid sequence of the protein. This can happen due to the redundancy of the genetic code, where multiple codons can code for the same amino acid. As a result, some mutations can occur without affecting the organism's traits.
