Question

Red blood cells are normally circular in shape. Sickle cell anemia is a disorder that affects the shapes red blood cells causing them to be sickleshaped (like a crescent moon). Beta hemoglobin normally consists of a chain of 147 amino acids (441 base pairs of DNA). In patients with sickle cell anemia, the beta hemoglobin still has 147 amino acids, yet one amino acid is different. The table below shows a section of the amino acid sequence : Based on the data provided of amino acid sequences and the shape difference between normal red blood cells and those with the sickle cell mutation , which of the following interpretations of data best explains these differences?

A substitution in the DNA sequence caused the difference in amino acid 3, other
substitutions may have occurred in order to complete the drastic shape change.
A single substitution in the DNA sequence caused the difference in amino acid 3,
