All other amino acids are identical to a normal hemoglobin molecule. Based on the information above, which of the following mutations is the most likely cause of sickle-cell anemia?
a. A single base-pair substitution in the gene encoding the beta subunit. b. A single base-pair insertion in the gene encoding the beta subunitc. A single base-pair deletion in the gene encoding the beta subunit
