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 answer

To determine the tRNA anticodon that pairs with the mRNA codon AUU, we need to find the complementary bases.

The mRNA codon AUU consists of:

  • A (adenine) pairs with U (uracil)
  • U (uracil) pairs with A (adenine)
  • U (uracil) pairs with A (adenine)

Therefore, the sequence of bases on the tRNA anticodon that pairs with the mRNA codon AUU would be UAA.
