Thalassemia and sickle cell anaemia are caused due to a problem in globin molecule synthesis. Select the correct statement.
Options
- ABoth are due to a qualitative defect in globin chain synthesis
- BBoth are due to a quantitative defect in globin chain synthesis
- CThalassemia is due to less synthesis of globin molecules
- DSickle cell anemia is due to a quantitative problem of globin molecules
Correct answer
C. Thalassemia is due to less synthesis of globin molecules
Step-by-step solution
Thalassemia differs from sickle-cell anaemia in that the former is a quantitative problem of synthesizing too few globin molecules while the latter is a qualitative problem of synthesizing an incorrectly functioning globin.
