The correct response is:

The mutated sequence still codes for the same amino acid.

This occurs due to the redundancy in the genetic code, where multiple codons can code for the same amino acid. Therefore, some mutations, particularly those that are silent (do not change the amino acid sequence), do not have any effect on the characteristics of the organism.
