What evidence shows that the genetic code is not overlapping?
A)Mutant proteins whose genes experience a change in only one nucleotide,have a corresponding change in 3 consecutive amino acids.
B)Mutant proteins whose genes experience a change in only one nucleotide,have a corresponding change in only 1 amino acid.
C)Mutant proteins are greatly increased in length relative to the gene coding for them.
D)Mutant proteins are greatly decreased in length relative to the gene coding for them.
E)Mutant proteins whose genes experience a change in only one nucleotide,have a corresponding change in 6 consecutive amino acids.

Question

Quizplus · Accepted Answer

If the genetic code was overlapping, a change in one nucleotide would affect multiple amino acids, not just one. Therefore, the fact that a change in one nucleotide only affects one amino acid in mutant proteins suggests that the genetic code is not overlapping.
