Question
Based on the sequence of this mRNA, what is the sequence of the tRNA anticodon that would add an amino acid to the N-terminus of the translated polypeptide sequence?5’ …GAA – CCC – ACG – UGU - UAU… 3’Group of answer choices5’ AUA 3’5’ UAU 3’5’ UUC 3’5’ GAA 3’
Solution
The sequence of the tRNA anticodon that would add an amino acid to the N-terminus of the translated polypeptide sequence would be 5' CUU 3'.
Here's the step-by-step process:
-
The mRNA sequence given is 5’ …GAA – CCC – ACG – UGU - UAU… 3’.
-
The N-terminus of the translated polypeptide sequence is determined by the first codon in the mRNA sequence, which is GAA.
-
In tRNA, the anticodon is the sequence of nucleotides that pairs with the mRNA codon. The anticodon is complementary to the codon.
-
Therefore, the anticodon for the mRNA codon GAA would be CUU.
Please note that the anticodon is written in the 5' to 3' direction.
