Question

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?

Select {responseValue}
Amino acids have similar functions, so their corresponding proteins are unaffected by mutations.

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

Select {responseValue}
One amino acid substitution does not affect protein synthesis.

Select {responseValue}
Only mutations that occur at the chromosomal level change protein function.

Answer 1

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

(Explanation: a silent mutation changes the DNA codon but still codes for the same amino acid because the genetic code is degenerate.)
