A DNA mutation results in a protein that is the same as the initial protein synthesized before the mutation. Which statement BEST explains this outcome?

• One amino acid substitution does not affect protein synthesis.

• Different codons can be translated into the same amino acid, so some mutations do not affect protein synthesis.

• Only mutations that occur at the chromosomal level change protein function.

• Amino acids have similar functions, so their corresponding proteins are unaffected by mutations.
