Question

The piece of rna below includes the region that codes for the binding site for the initiator trna needed in translation. 5′-guuucccguauacaugcgugccgggggc-3′ which amino acid will be on the trna that is the first to bind to the a site of the ribosome?

Answer 1

The answer is valine. This is because the amino acid is coded for by codons GUU, GUC, GUA, and GUG. The tRNA will have CAA, CAG, CAU, or CAC anticodons so that it can identify the above codon in the mRNA during translation in the ribosome.
