if the sequence of bases on the mrna codon is auu, what would be the sequence of bases on the opposite strand assembled by the trna? (1 point)
○ att
○ uua
○ taa
○ uaa

Explanation:

In RNA, the base pairing rules are A (adenine) pairs with U (uracil), and U pairs with A, C (cytosine) pairs with G (guanine) and G pairs with C. The tRNA anticodon is complementary to the mRNA codon. The mRNA codon is AUU. So, for each base: A (in mRNA) pairs with U (in tRNA), U (in mRNA) pairs with A (in tRNA), and U (in mRNA) pairs with A (in tRNA). So the tRNA anticodon sequence is UAA.

Answer:

D. UAA
