What type of mutation occurred?

AUG CCU AAU GCU UGA (Remember: A↔U, T↔A, C↔G in transcription) Level 2: Codon Chart (Translation Start) mRNA codons: AUG CCU AAU GCU UGA

UAC (Anticodon is complementary to mRNA codon, same base pairing rules as DNA→RNA but with U) Level 4: Mutations Original DNA: TAC GGA TTA CGA ACT Mutated DNA: TAC GGA TTT CGA ACT

Met – Pro – Asn – Ala – Stop (Start codon AUG = Methionine; Stop codon UGA ends translation) Level 3: tRNA Anticodons Given mRNA codon: AUG Question: What is the tRNA anticodon?

Use the codon wheel/chart. What is the amino acid sequence?

What is the mRNA sequence?
