20. For tRNA to do its job, each tRNA molecule must be attached to the correct amino acid that
corresponds to the anticodon in that type of tRNA. To know which amino acid should be attached
to each tRNA molecule, use the base pairing rules to complete this table.

Cytoplasm: Use this table to match each model tRNA molecule with the correct amino acid for
that type of tRNA Tape the amino acid to the tRNA very lightly, because they will only be
joined temporarily and will soon separate.
Note: Each model tRNA molecule only shows the three nucleotides of the anticodon and the
binding site for the amino acid. A real tRNA molecule has many more nucleotides. Similarly, a
