Thalassemia and sickle cell anemia are caused due to a problem in globin molecule synthesis. Select the correct statement:
Correct answer: B. Thalassemia is due to less synthesis of globin molecules
- A. Both are due to a quantitative defect in globin chain synthesis
- B. Thalassemia is due to less synthesis of globin molecules
- C. Sickle cell anaemia is due to a quantitative problem of globin molecules
- D. Both are due to a qualitative defect in globin chain synthesis
Explanation
Sickle cell anemia is caused due to point mutation in which at the 6th position of the beta-globin chain, glutamic acid is replaced by valine. Thus, it is a qualitative defect in the functioning of globin molecules. Sickle cell anemia is caused due to point mutation in which at the 6th position of the beta-globin chain, glutamic acid is replaced by valine. Thus, it is a qualitative defect in the functioning of globin molecules. Thalassemia is caused due to either mutation or deletion which ultimately results in a reduced rate of synthesis of one of the globin chains that make up hemoglobin. Hence, it is a quantitative defect in the functioning of globin molecules.ing of globin molecules.

About Chromosomes
Chromosomes are DNA-protein structures that carry genes and become visible during cell division. Coverage includes chromatin, centromeres, sister chromatids, homologous chromosomes, chromosome number, and the distinction between diploid and haploid cells, with links to DNA replication, mitosis and meiosis.
