93. Thalassemia and sickle cell anemia are caused dueto a problem in globin molecule synthesis. Selectthe correct statement.
(1) Both are due to a qualitative defect in globinchain synthesis
(2) Both are due to a quantitative defect in globinchain synthesis
(3) Thalassemia is due to less synthesis of globinmolecules
(4) Sickle cell anemia is due to a guantitativeproblem of globin molecules

Answer 1

Answer:

I think Answer 2 is correct

Answer 2

Thalassemia and sickle cell anemia are caused due to a problem in globin molecule synthesis. The correct statement is:

(3) Thalassemia is due to less synthesis of globin molecules.

Thalassemia

• Thalassemia is an inherited blood disorder.

• In this disorder, the body makes an inadequate amount of hemoglobin. The reason for this is the mutations in the DNA of cells that make hemoglobin.

• It occurs due to less synthesis of globin molecules.

Sickle cell anemia

• Sickle cell anemia is called sickle cell disease.

• It is also an inherited blood disorder.

• In this disorder, the round red blood cells get distorted to a sickle shape.
