Solution
The sequence of the tRNA anticodon that would add an amino acid to the C-terminus of the translated polypeptide sequence is 5’ AAC 3’.
Here's the step-by-step explanation:
-
The mRNA sequence given is 5’ …CGU – CGC – ACG – UUG… 3’.
-
The tRNA anticodon is the sequence of nucleotides that pairs with the mRNA codon.
-
The tRNA anticodon is complementary to the mRNA codon. This means that wherever there is a C in the mRNA, there will be a G in the tRNA, and vice versa. Similarly, wherever there is an A in the mRNA, there will be a U in the tRNA, and vice versa.
-
The last codon in the mRNA sequence is UUG.
-
Therefore, the tRNA anticodon that pairs with this mRNA codon is AAC.
So, the correct answer is 5’ AAC 3’.
