Codon Bingo

Introduction:

DNA is simply a storage form of information, like a recipe book.  In order to make useful proteins from this recipe, we must first transcribe the selected recipe from the DNA into messenger RNA (m-RNA) which then leaves the nucleus & goes to the ribosomes where it is "read" to link amino acids (building blocks of proteins). The code is "read" three bases at a time called a codon. The triplet code allows for a total of 4x4x4 or 64 different codons (groups of three RNA bases) --far more than needed to code for 20 amino acids. It was discovered that each amino acid is coded for by more than one codon. Codon Bingo is a simple exercise to learn how to use a codon table to translate mRNA into its associated amino acids.

Materials:  Bingo cards, pencil, codon table, beans or pennies

Procedure:

1. Pass out blank bingo cards.

2. Students should fill out each of the blanks with an amino acid from the codon chart.

3. Teacher will call out 3 bases (A, T, G, C)

4. Students find the amino acid that is associated with the codon and mark the square (use bingo chips, pennies, beans, or other miscellaneous items)
