Q165 / 180 · NEET 2017 · Zoology

Thalassemia and sickle cell anaemia 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
  • Correct answer
    C
    Thalassemia is due to less synthesis of globin molecules
  • D
    Sickle cell anemia is due to a quantitative problem of globin molecules

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.

Hence, the correct answer is option: 'C'.
