Question: Over 100 different kinds of mutant hemoglobin molecules have been
Over 100 different kinds of mutant hemoglobin molecules have been detected in humans. Unlike sickle cell anemia, not all of these mutations are as serious. In one nonlethal mutation, glutamine substitutes for a single glutamic acid in normal hemoglobin. Rationalize why this substitution is nonlethal.
