Q. Thalassemia and sickle cell anemia are caused due to a problem in globin molecule synthesis. Select the correct statement.
A) Both are due to a qualitative defect in globin chain synthesis.
B) Both are due to a quantitative defect in globin chain synthesis.
C) Thalassemia is due to less synthesis of globin molecules.
D) Sickle cell anemia is due to a quantitative problem of globin molecules.
Explanation
[Solution] Thalassemia is a quantitative defect (too few globin chains); sickle-cell anaemia is qualitative (abnormal globin). Answer (3).
