Part A -tRNA interactions with mRNA and the ribosome

Ribosomes provide the scaffolding on which tRNAs interact with mRNA during translation of an mRNA sequence to a chain of amino acids. A ribosome has three binding sites, each of which has a distinct function in the tRNA-mRNA interactions.

Drag the appropriate tRNAs to the binding sites on the ribosome to show the configuration immediately before new peptide bond forms. Note that one of the binding sites should be left empty.
