A. Globin is a red blood cell protein that is responsible for oxygen transport. The amino acid

sequence for a portion of the globin protein is Proline, Glutamic Acid, Glutamic Acid, Lysine. Write

the mRNA sequence of the amino acids for these amino acids in the space below (note, you don't

have to write all possible mRNA combinations for each amino acid, simply choose one correct codon

each amino acid specified above).

B. How many nucleotides would it take to code for the four amino acids in the above question.

Explain your answer.
