Hemoglobin and sickle cell anemia, 3D animation with no audio

Description:
This animation shows hemoglobin proteins of a person with sickle cell anemia. Sickle cell anemia is caused by a single code leeter change in the DNA. This in turn alters one of the amino acids in the hemoglobin protein. Valine sits in the position where glutamic acid should be. The valine makes the hemoglobin molecules stick together, forming long fibers that distort the shape of the red blood cells causing the characteristic sickle shape of the red blood cells.

The HBB gene encodes an important blood protein called beta globin. A person with beta-thalassemia carries a mutation in both copies of the HBB gene, completely halting production of the beta globin protein.
