What is the correct tRNA anti-codon for the mRNA codon 5′-GCA-3′? 5′-UGC-3′ 3′-UGC-5′ 5′-CGT-3′ 3′-CGT-5′ 5′-CGU-3′

• 5'-UGC-3'

Explanation:

5'-GCA-3'

3'-CGU -5'

Each tRNA contains a distinction anticodon triplet sequence which pairs with amino acid codons.

tRNA is responsible in adding amino acids by using mRNA codons within the ribosome

A pairs with U

G pairs with C

5-GCA-3' would be recognized by tRNA anticodon 3-CGU-5' or when reversed 5'-UGC-3'
