Answer 1

To determine the sequence of bases on the tRNA that would pair with the mRNA codon AUU, we first need to consider how base pairing works between mRNA and tRNA.

In mRNA:

• Adenine (A) pairs with Uracil (U)
• Uracil (U) pairs with Adenine (A)
• Cytosine (C) pairs with Guanine (G)
• Guanine (G) pairs with Cytosine (C)

Given the mRNA codon AUU, we can find the corresponding tRNA anticodon by pairing:

• A (from AUU) pairs with U (on tRNA)
• U (from AUU) pairs with A (on tRNA)
• U (from AUU) pairs with A (on tRNA)

Therefore, the tRNA anticodon that pairs with the mRNA codon AUU is UAA.

Thus, the answer is: UAA
