Vedclass · Answer

(A) Sickle-cell anaemia is a classic example of a point mutation.It occurs due to a single base pair substitution in the gene coding for the $\beta$-globin chain of haemoglobin.Specifically, the codon $GAG$ is replaced by $GUG$, which leads to the substitution of glutamic acid with valine at the sixth position of the $\beta$-globin chain.Therefore, $A$ is point mutation and $B$ is $\beta$-chain.

Sickle-cell anaemia happens due to $A$ mutation in which $B$ of haemoglobin is affected. Fill the correct option for $A$ and $B$.
