To find the sequence of bases on the opposite strand assembled by the tRNA, we need to use the complementary base pairing rules. The base pairs are as follows: A (adenine) pairs with U (uracil) in RNA, and T (thymine) in DNA pairs with A (adenine).
In this case, the mRNA codon is AUU. To find the corresponding bases on the opposite strand, we need to replace each base with its complementary base.
The mRNA base A will pair with U (uracil), so A is replaced by U. The mRNA base U will pair with A (adenine), so U is replaced by A. Lastly, the mRNA base U will pair with A (adenine), so U is replaced by A.
Following these complementary base pairing rules, the sequence of bases on the opposite strand assembled by the tRNA is UAA.
