Protein Synthesis
Directions: Fill in the charts below for each of the following sequences. Fill in the DNA,
the mRNA sequence, the tRNA anticodons, or the amino acid sequences (3 letter
abbreviations) that have been left blank. Use the amino acid circle chart to assist you.
You may also use the square charts in the lesson material if this is easier for you.
*Remember, the mRNA codon is what is used to find the amino acids on the amino acid
chart – not the tRNA!
