Activity 3.2.2: The Genetic Code Introduction In the previous activity, you learned how DNA encodes the instructions for creating proteins. You also learned about the basics of the process of protein synthesis. In this activity you will apply your knowledge of transcription and translation to decode a secret message as well as investigate the effect that various mutations have on protein production. You will then look specifically at the genetic mutation that causes sickle cell disease.

(Note that the gene coding for hemoglobin is 146 amino acids. In this activity you will only work with a small portion of this gene.) You will use a codon chart to determine the amino acids that correspond to the mRNA sequence. Codon charts are often
