Question 1
A class of mutations that results in multiple contiguous (side-by-side) amino acid changes in proteins is probably caused by which one of the following types of mutations?
◦ base analog
◦ frameshift
◦ recombinant
◦ transversion
◦ transition
Question 2
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 ________.
◦ the code contains internal punctuation
◦ AUG is the initiating triplet
◦ the code is triplet
◦ there are three amino acids per base
◦ the code is overlapping
