Objective:  To determine the amino acid sequence that would be produced by the mRNA created in the RNA Translation Activity

 

Materials:

Your mRNA model                             

mRNA Codon - Amino Acid Table

 

Procedure:

1.   Beginning with the 1st three bases on your mRNA model, use the table below to determine what amino acid each mRNA codon will code for.

2.   Write the amino acid chain produced in the space provided for Conclusion #1.
