Sickle Cell Is A Homogenous Genetic Anemia Caused When An Abnormal Gene (Hemoglobin S Or Hbs) Causes The Substitution Of The Amino Acid Valine, For Another, Glutamic Acid (Amundsen Et Al., 1984).

It Occurs Due To The Substitution Of Valine Amino Acid With Glutamic Acid.

We may state that the amino acid sequence for hemoglobin has changed because one amino acid has been modified in sickle cell anemia. In sickle cell anemia the 6th amino acid is changed from glutamic acid to valine in the protein hemoglobin. Taking the one aberrant peptide and analyzing it one amino acid at a time, ingram showed that sickle cell hemoglobin differed from normal hemoglobin by a single amino acid, the number 6 position in the beta chain of hemoglobin.
