Codon Charts
Codon Charts
Codon Bingo
• I will read an mRNA codon.
• You will translate the codon to determine
which amino acid it codes for using your
codon chart.
• If you have that amino acid on your card, write
the mRNA codon I said in that space using a
dry erase marker.
• Once, you have bingo, say BINGO!
Breaking the Code
1. Use your notes to help you complete the
Breaking the Code practice handout.
2. If you have questions, please raise your hand
so I can come around and help you.
Breaking the code Handout
Given the following:
1. DNA strand – TAC-AAA-TTT-CCC-GGG-ATA
2. mRNA strand – AUG-CAU-UAG-GGA-UUA-GGA

4. DNA strand – TAC-TTC-ACG-GAT-TAG-GTC
5. mRNA strand – AUG-AAG-UUG-UAG-GGU-CCU
Solve for the Amino Acid for each problem (1-5).
