In order for life to function, DNA must be used as a blueprint to synthesize proteins. In patients with cystic fibrosis, the mutated CFTR nucleotide has a DNA blueprint that
causes the synthesis of the incorrect protein. According to the DNA segment in Source 4,
Abby and John created the below amino acid sequences. Analyze their sequences and
determine which amino acid sequence is incorrect for the Normal CFTR nucleotide
sequence and explain why it is wrong using your knowledge of protein synthesis.
Abby's Sequence:
Phe Phe Phe Gly Val
John's Sequence:
