Vedclass · Answer

(A) point mutation is a genetic mutation where a single nucleotide base is changed,inserted,or deleted from a sequence of $DNA$ or $RNA$.Sickle cell anemia is a classic example of a point mutation.In this condition,a single base substitution (a transversion) occurs in the gene for the $\beta$-globin chain of hemoglobin.Specifically,the codon $GAG$ is mutated to $GUG$,which results in the substitution of the amino acid glutamic acid with valine at the $6^{th}$ position of the $\beta$-globin chain.
