α-thаlаssemiа is anоther blооd disorder in which abnormal hemoglobin molecules are formed, leading to anemia. One mutant allele known to cause α-thalassemia occurs in α-hemoglobin and is called Constant Spring. Normal α-hemoglobin is 141 amino acids long, while the Constant Spring protein is 172 amino acids long. Include answers to both A and B in your response. A maximum of 2 sentences per part. A) Explain how a frameshift mutation in the coding region of α-hemoglobin could result in the Constant Spring protein. (5 pts) B) Explain how a single base-substitution mutation in the coding region of α-hemoglobin could result in the Constant Spring protein. (5 pts)
