An Amino Acid Code.
To the left is shown twenty amino acids with their one and three-letter
abbreviations.
1. Choose a partner at another table and write a short message to that partner
using only the letters included in the single letter abbreviations for amino
acids (no B, J, O, U, X, or Z). Write your message here:
2. Translate your note into three-letter abbreviations using the table to the
left. Write your sequence of amino acids here:
2. Use the genetic code on p303 to figure out the mRNA sequence that
would code for your message. Write the mRNA sequence here:
3. Write the DNA code that would generate the mRNA sequence you wrote
in step 2:
4. Now copy that DNA sequence on a small strip of paper and give it to your
partner at another table.
5. Copy your partner’s DNA sequence here:
6. Transcribe it to mRNA:
7. Use the genetic code on p303 to translate the mRNA sequence to amino
acids and write the three-letter abbreviation for each amino acid here:
8. Decode your partner’s message by writing the single-letter abbreviations
for the amino acids here:
