Using the table above and the mRNA transcript AUG-CUC-UAC-AAG-UAG, choose the false statement: XXX The protein encoded for by the transcript above would appear as met-leu-tyr-glu. The segment of DNA from which the mRNA segment above was transcribed would have had the following sequence: TAC-GAG-ATG-TTC-ATC. a mutation that changes the codon UAC to UAU wouldn't have any effect on the primary structure of the protein it codes for. A TRNA with the anticodon UUU will carry the amino acid lysine (Lys).

Question
Choose the false statement
Using the table above and the mRNA transcript AUG-CUC-UAC-AAG-UAG, choose the false statement: - The protein encoded for by the transcript above would appear as met-leu-tyr-glu. - The segment of DNA from which the mRNA segment above was transcribed would have had the following sequence: TAC-GAG-ATG-TTC-ATC. - A mutation that changes the codon UAC to UAU wouldn’t have any effect on the primary structure of the protein it codes for. - A tRNA with the anticodon UUU will carry the amino acid lysine (Lys). ### Options: 1. The protein encoded for by the transcript above would appear as met-leu-tyr-glu. 2. The segment of DNA from which the mRNA segment above was transcribed would have had the following sequence: TAC-GAG-ATG-TTC-ATC. 3. A mutation that changes the codon UAC to UAU wouldn’t have any effect on the primary structure of the protein it codes for. 4. A tRNA with the anticodon UUU will carry the amino acid lysine (Lys). ### Explanation - The diagram/tabular section appears to be a standard codon chart, which translates mRNA codons into amino acids. - The provided mRNA sequence translates to methionine-leucine-tyrosine-lysine, with the codon UAG being a stop codon. - The correct DNA sequence, complementary to the mRNA, should be TAC-GAG-TAC-TTC-ATC (not the one provided, which seems incorrect). - The codon UAC codes for tyrosine, and changing UAC to UAU will result in the same amino acid due to redundancy in the genetic code. - The anticodon UUU on tRNA would pair with the codon AAA and carry lysine (incorrect as depicted in the statement).
