WebThe structural difference between a normal hemoglobin molecule and a sickle cell molecule—which dramatically decreases life expectancy—is a single amino acid out of 600. What is even more remarkable is that three nucleotides each encode those 600 amino acids and a single base change (point mutation)—1 in 1800 bases—causes the mutation. WebHemoglobin. The amount of Hb F present is a function of the number of reticulocytes that contain Hb F, the extent of selective survival of Hb F–containing reticulocytes that become mature Hb F–containing erythrocytes (F cells), and the amount of Hb F per F cell.
