Book problem 28-22: Human and horse insulin both have two polypeptide chains, with one chain containing 21 amino acids and the other containing 30 amino acids. They differ in primary structure at two places. At position 9 in one chain, human insulin has Ser and horse insulin has Gly; at position 30 in the other chain, human insulin has Thr and horse insulin has Ala. How must the DNA for the two insulins differ? Book problem 28-24: The codon UAA stops protein synthesis. Why does the sequence UAA in the following stretch of mRNA not cause any problems? Provide a 1-2 sentence response. -GCA-UUC-GAG-GUA-ACG-CCC- For what amino acids do the following ribonucleotide triplets code?
