Directions:
1. Transcribe the DNA into mRNA
2. Find the “start codon”; using the mRNA codon chart, translate the mRNA to determine the order
of amino acids.
3. Using the table of proteins below the codon chart, write the name of the protein made.

Questions:
1. How many different amino acids are there? Give three examples.
2. Is the order of amino acids important in the expression of the correct protein?
Explain.
3. In this activity, you used a table to determine which codon coded for which amino
acids. In your cells, how does the ribosome get these amino acids?
