Practice Question

A mutation of a portion of a DNA molecule changed the resulting mRNA sequence from AUU-GGG-UUC to CUU-GGG-UUC. Using the table below, predict the resulting amino acid sequence.

Answer Choices:

Correct Answer:

From Ile-Gly-Phe to Leu-Gly-Phe

Rationale:
To decode the mRNA sequences: • Original mRNA sequence: AUU-GGG-UUC Using the codon table: • AUU = Ile • GGG = Gly • UUC = Phe So, original sequence = Ile-Gly-Phe • Mutated mRNA sequence: CUU-GGG-UUC Using the codon table: • CUU = Leu • GGG = Gly • UUC = Phe So, mutated sequence = Leu-Gly-Phe
