Question

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

Answer 1

The correct option is C

Thalassemia is due to less synthesis of globin molecules

The correct option is C

Explanation of the correct option:

1. Both thalassemia and sickle cell anaemia are inherited illnesses that affect the production of haemoglobin.
2. There is a deficiency in the globin chain in thalassemia.
3. As a result of the decreased synthesis of globin molecules, aberrant red blood cells are formed.

Explanation of the incorrect option:

Option A:

Thalassemia is a quantitative fault in which there is insufficient globin chain production, whereas sickle cell anaemia is a qualitative defect in which the globin chain's functioning is altered.

Option B:

Thalassemia is quantitative whereas sickle cell anemia is a qualitative defect.

Option D:

Sickle cell anaemia is a kind of anaemia in which the function of the globin chain is disrupted.

Final answer: Thalassemia is due to less synthesis of globin molecules is the correct statement.
