To determine the correct tRNA anticodon sequence that pairs with the mRNA codon AUU, we need to consider the complementary base pairing that occurs during translation.
In RNA, adenine (A) pairs with uracil (U), and uracil (U) pairs with adenine (A). Cytosine (C) pairs with guanine (G), and guanine (G) pairs with cytosine (C).
Given the mRNA codon AUU:
- A pairs with U
- U pairs with A
- U pairs with A
Thus, the sequence of bases on the tRNA anticodon that would assemble is: UAA.
So, the correct response is UAA.
