Biology Question on Mendelian Disorders
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 quantitative defect in globin chain synthesis
B
Thalassemia is due to less synthesis of globin molecules
C
Sickel cell anemia is due to a quantitative problem of globin molecules
D
Both are due to a qualitive defect in globin chain synthesis
Answer
Thalassemia is due to less synthesis of globin molecules
Explanation
Solution
Thalassemia differs from sickle-cell anaemia in that
the former is a quantitative problem of synthesising too few globin molecules while the latter is a qualitative problem of synthesising an incorrectly functioning globin.
