WebThis single mutation causes the amino acid valine to be encoded rather than glutamic acid. This one change has a critical effect on the structure of the hemoglobin molecule, causing the condition known as sickle cell anemia. Another type of mutation is a frameshift mutation. This occurs when a base is added to or deleted from a DNA sequence.
