Hemoglobin is a complex protein that contains four polypeptide chains. The normal hemoglobin found in adults-called adult hemoglobin-consists of two alpha and two beta polypeptide chains, which are encoded by different loci. Sickle-cell hemoglobin, which causes sickle-cell anemia, arises from a mutation in the beta chain of adult hemoglobin. Adult hemoglobin and sickle-cell hemoglobin differ in a single amino acid: the sixth amino acid from one end in adult hemoglobin is glutamic acid, whereas sickle-cell hemoglobin has valine at this position. After consulting the genetic code provided in Eigure 15.10 , indicate the type and location of the mutation that gave rise to sickle-cell anemia.
