1) A wild-type polypeptideconsists of 27 amino acids. Many mutants have been discovered that produce versions of this polypeptide that are longer than normal.These mutations are each due to a substitution of a singlebase.
a. What kind of mutation isresponsible?
b. Do you expect the first 27amino acids in the mutant polypeptides to have the same sequence asthat in the wild type? Why or why not?
c. Consult the genetic codeto determine what amino acids could occupy the 28th position in the mutant polypeptides.
