Final answer:
The tRNA with an anticodon 5'-CUU-3' is expected to carry the amino acid leucine, as the complementary mRNA codon for this anticodon is 3'-GAA-5', which codes for leucine according to the standard genetic code.
Step-by-step explanation:
The amino acid that you would expect a tRNA with the anticodon 5'-CUU-3' to carry is leucine. In the genetic code, the anticodon of tRNA is complementary to the mRNA codon. The mRNA codon that pairs with the anticodon 5'-CUU-3' would be 3'-GAA-5', which codes for leucine. This is based on the standard genetic code, where GAA corresponds to the amino acid leucine. The process of translation relies on this complementary base pairing, ensuring the correct sequence of amino acids in the forming polypeptide chain. The anticodon arm of a tRNA molecule contains a sequence of three nucleotide bases that are complementary to the mRNA codon for its particular amino acid.
