Question

Quizplus · Accepted Answer

If the genetic code were overlapping, a mutation in one nucleotide would result in a change in more than one amino acid. However, the evidence shows that a change in one nucleotide results in a change in only one amino acid, indicating that the genetic code is not overlapping. Choice B is the only option that reflects this evidence.
