The tRNA anticodon 3'-UAC-5' will pair with the mRNA codon

5'-AUU-3'

5'-UAC-3'

5'-AUG-3'

3'-GUA-5'

5'-AUG-3'

The tRNA anticodon 3'-UAC-5' will pair with the mRNA codon 5'-AUG -3'. The tRNA acts as an adapter molecule, that would on one hand read the code and on other hand would bind to specific amino acids. tRNA has an anticodon loop that has bases complementary to the code. It also has an amino acid acceptor end to which it binds to amino acids.
