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? (a) One amino acid substitution does not affect protein synthesis. (b) Different codons can be translated into the same amino acid, so some mutations do not affect protein synthesis. (C) Only mutations that occur at the chromosomal level change protein function. (C) Amino acids have similar functions, so their corresponding proteins are unaffected by mutations.

Answer 1

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