Sickle-cell anaemia

Vedclass · Answer

(D) The correct answer is $D$. Sickle-cell anaemia is a classic example of a molecular disease caused by a point mutation in the gene encoding the $\beta$-globin chain of haemoglobin.This mutation results in the substitution of glutamic acid with valine at the $6^{th}$ position of the $\beta$-globin chain.This change in the amino acid sequence alters the molecular structure of the haemoglobin protein,causing the red blood cells to become sickle-shaped under low oxygen tension.
