Beta Thalassemia Anemia is Caused by What Type of Mutation

Question

Beta thalassemia anemia is caused by what type of mutation in the globin gene?  
A) Base-pair substitution
B) Deletion
C) Insertion
D) Dimerization
E) Promoter interference

Accepted Answer

Beta thalassemia is caused by deletions or mutations in the beta globin gene, which disrupts the production of beta globin chains in hemoglobin. Base-pair substitutions, insertions, dimerization, and promoter interference may also cause other types of genetic conditions, but they are not typically associated with beta thalassemia.
