In Thalessemia disease, human body becomes incapable of producing?

Accepted Answer

Haemoglobin. In Thalessemia disease, human body becomes incapable of producing haemoglobin. It is a blood disorder passed down through families (inherited) in which the body makes an abnormal form or inadequate amount of hemoglobin. Hemoglobin is the protein in red blood cells that carries oxygen. The disorder results in large numbers of red blood cells being destroyed, which leads to anemia. Haemoglobin is made of two proteins: * Alpha globin * Beta globin Thalassemia occurs when there is a defect in a gene that helps control production of one of these proteins.There are two main types of thalassemia: * Alpha thalassemia occurs when a gene or genes related to the alpha globin protein are missing or changed (mutated). * Beta thalassemia occurs when similar gene defects affect production of the beta globin protein.
