Η θαλασσαιμία παρουσιάζει ανώμαλη αιμοσφαιρίνη και άνιση παραγωγή αλυσίδων σφαιρίνης. Diagram explaining blood disorders: sickle cell anemia, thalassemia, and methemoglobinemia. Visuals illustrate red blood cell shapes, genetic mutations in? -globin genes, and molecular structures. Sickle cell displays crescent-shaped cells due to point mutations. Thalassemia shows abnormal hemoglobin and unequal? ? globin chain production. Methemoglobinemia is depicted with altered iron oxidation states. Molecular models highlight changes in iron and oxygen transport. Text annotations describe mutations and molecular effects on hemoglobin function.
