Question

Drag the appropriate tRNAs to the binding sites on the ribosome to show the configuration immediately before a new peptide bond forms. Note that one of the binding sites should be left empty.Figure:Ribosome structure in figure

Answer 1

Note: Question is incomplete lacking figure. I have added figure with question and answer.

Answer:

E site will be empty as it is exit site for protein synthesis.

P site will have code AUA with three amino acids  because it is the site for peptide synthesis.

A site will have UCC code with one amino acid because its the code for serine synthesis. Moreover, A site is binding site for charged t-RNA molecules during protein synthesis.
