When scientists were attempting to determine the structure of the genetic code, Crick and coworkers found that when three base additions or three base deletions occurred in a single gene, the wild -type phenotype was sometimes restored. These data supported the hypothesis
That _.
A) the code contains internal punctuation
B) there are three amino acids per base
C) the code is triplet
D) AUG is the initiating triplet
E) the code is overlapping

Question

Quizplus · Accepted Answer

The restoration of the wild-type phenotype after three base additions or deletions suggests that the genetic code is read in sets of three bases, or triplets, which supports the hypothesis that the code is triplet.
