<span>The correct answer is A) a single amino acid may have more than one codon that translates for it.</span>
<span>This property of the codon is called codon degeneracy and is the redundancy of the genetic code. As a result, there is the multiplicity of three-base-pair codon combinations that specify an amino acid and that increases tolerance to point mutations (synonymous mutations). Usually, the codons encoding one amino acid differ in the second or third position.</span>
Vestigial structures<span> are often homologous to </span>structures<span> that are functioning normally in other species</span>
They are soluble. Often, they are of an appropriate polarity and size as well.
