Question

Identify the INCORRECT statement.

पर्याय

• Thalassemia is caused due to deletion or mutation of a gene which codes for the alpha (a) and beta (p) globin chains that result in the abnormal synthesis of hemoglobin.

• The synthesis of alpha chains are controlled by two closely linked genes (HBAl and HBA2) on chromosome 16.

• Synthesis of beta chain is controlled by a single gene (HBB) on chromosome 11.

• Sickle cell anaemia is a quantitative problem of synthesizing few globin molecules, while thalassemia is a qualitative problem of synthesizing an incorrectly functional globin.

Answer 1

Sickle cell anaemia is a quantitative problem of synthesizing few globin molecules, while thalassemia is a qualitative problem of synthesizing an incorrectly functional globin.

Explanation:

Thalassemia is a quantitative problem involving the production of a small number of globin molecules, whereas sickle cell anaemia is a qualitative problem involving the production of an incorrectly functioning globin.
