Shown below is the sequence of a coding strand of DNA that begins with what corresponds to the translation start codon (AUG) in the mRNA transcript. You are analyzing two different mutants. Mutant #1 has an extra C residue after the underlined G residue and Mutant 2 has a deletion of the underlined A residue.

Wild type 5’- ATGCTTACTGAGGTCATGGTACAGATGA

Mutant 1 5’- ATGCTTACTGCAGGTCATGGTACAGATGA

Mutant 2 5’- ATGCTTACTGAGGTCATGGTCAGATGA

What is the amino acid sequence of the polypeptide encoded by:

B. The wild type

C. Mutant 1

D. Mutant 2
